Oxygen Atom And Its Effects On The World

10. A pH scale describes the degree of acidity or alkalinity of a substance. 0 to 6.9 indicates an acidic solution, 7.1 to 14 indicates an alkaline solution, and 7 indicates a neutral solution.

Professor John Blamire of brooklyn.cuny.edu describes a single water molecule, the smallest part of a chemical element or compound that still shares the same chemical properties as defined by whatitis.com, as two 'slightly ' positive hydrogen atoms and one ' slightly ' negative atom together forming a hydrogen bond. In a water molecule, hydrogen atoms have a single electron and oxygen atoms have six electrons. The hydrogen atoms attach at a 107.5 degree angle and each share two electrons, one of theirs and one of the oxygen atom 's, to attach and

An example would be pure water. Most of the time the pH is determined by pH paper but there are also other ways to determine the pH. For example, in this lab, cabbage juice was used. Cabbage juice is a great pH indicator because it can be homemade and easy to access.

“The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity (sic) of the solution. The letters pH stand for power of hydrogen and the numerical value defined as the negative base 10 logarithm of the molar concentration of hydrogen ions.” (PH, 2002). The pH scale is from 0 to 14. When the pH is higher, the hydrogen ions are fewer and the substance considered alkaline. This means when a pH unit increases by one, there is a tenfold change in the hydrogen ion. For example, if a substance has a 7 pH, it has 10 times as many as hydrogen ions available as 8 pH. A lake having a water pH between 6.5 and 8.5 is considered to be neutral. Researchers tested Peckham Park lake water monthly from August 2015 to April 2016 for water pH levels. A water quality PH test strip taken from a jar and dipped into the lake. After a few minutes, the strip will turn a color and this color determines the pH. The jar the strips came in has a chart of the colors on the back which compared to the color on the strip. The lake tested monthly using the PH test strips, which show the pH level, hardness, toxic, etc. using color-change

pH is also known as a measure of hydrogen ions in a solution. A hydrogen ion is the nucleus of a hydrogen atom being split from its electron. Studying the pH of different types of soil being placed in a control group such as tap water will represent the acidity or alkalinity of the matter. The pH scale begins at 0 and goes all the way up to 14, pH 7 being its neutral point, which isn’t acidic or basic. A neutral point on the acidic scale is in the middle, anything lower than the neutral point (7), is acidic, and anything higher than the neutral point is considered basic or “alkaline”.

Acids are a corrosive substance with a pH less than 7. Acidity is caused by a high concentration of hydrogen ions.

When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH, which stands for the proportion of hydrogen ions in a solution, could be acidic (acidosis), neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral;

An acid is a chemical substance that typically has a corrosive or sour-taste and turns litmus paper red. It has a pH of below 7 and can generally dissolve some metals or even neutralize alkalis. A base on the other hand, is the opposite. They have a bitter taste and are very aqueous. Their pH rating is above 7 and they turn litmus paper blue. In science, pH is the negative log of the activity of the hydrogen ion in an aqueous solution. Basically, we find the pH of a substance by using a testing strip or litmus paper to see the amount of H+ atoms in it. Litmus paper, a common indicator, is used to easily test the pH level of a substance. We can see how acidic or basic a substance is by comparing it to others on a pH scale. A pH scale ranges from 0-14, the most acidic being 0 and most basic being 14. Lemon juice, for example, has a pH of 2 meaning its very acidic. However, average dish soap has a pH of 7-8. The only thing left is a pH level of exactly 7. A pH of 7 is perfectly neutral, not acidic or

Explain the pH scale and how it is used to indicate acidic, alkaline, and neutral solutions.

One of the tests we conducted while I was at Lake Tonetta we learned about pH. Why is pH so important? pH is a good indicator of the lakes healthiness.pH is a way to measure how acidic or how alkaline a body of water pH scale goes from 0-14 a zero is the strongest acid.  A reading of 14 would be the strongest base. Pure water is considered neutral-rather an acid or a base with a pH reading of 7 Indicator measure the pH in watersheds to determine whether the water is acidic/neutral, or base.Most living things have adapted to a life in water with specific pH. If the pH changes the organisms may die. The best pH for water is between 6.5-7.5 right near neutral. The pH we tested on November 3, 2016, was 7.This is excellent because all creatures can live in that water it is the healthiest it can be.

Water has the properties of a polar molecule, meaning that it is imbalanced in its electrons. The hydrogen ions in water are positive and the single oxygen ion is extremely negative. The extremely negative oxygen ion prevails over the positive hydrogen ion, masking the positivity. Like an oxygen ion, the lives of Haitians are negative but others overlook the hydrogen that exist in their experiences. The people of Haiti are similar to water molecules because they face negativity, but unlike a water molecule they overcome it.

While if water with a pH above seven (basic) will not cause the person who consumes it any health effects. It will just have an alkaline taste which may not be pleasing to the consumer. pH is extremely important to our cells as a slight change in pH in our cells can be harmful. For example, if the pH of human blood is not maintained, the person will end up dying in a few minutes. pH is also important to the environment. For example, if precipitation becomes acidic (a pH of less than 5.6 is considered acidic precipitation), it can kill some organisms in the environment by interfering with the organisms’ chemical processes of life. If water is contaminated, it can be fatal for one to drink. Usually, water is contaminated with contaminants such as copper, lead, iron, sodium and bacteria. If water is contaminated with higher level of sodium than there is water, and a person drinks it for a long period of time, it will be unsafe, and most likely fatal to the person. This is because the person’s cells will shrivel up as they are drinking a hypertonic solution. Thus if one were to drink water with a high sodium concentration than there is water, they will eventually end up being dehydrated, (due to their cells shrivelling up) and face an inevitable death if they continue to drink the water that has a high concentration of salt. Also if a person drinks water that is

In this experiment different pH levels ranging from 3 to 11 were used to test the effects on daphnia heart rate. The pH scale ranges from 0 to 14. A pH ranging from 0 to 6 is acidic, a pH of 7 is neutral, and a pH higher than 7 ranging from 8 to 14 is basic. PH revolves around hydrogen ions (H+). The reason pH levels can be acidic, basic, or neutral is because acids give hydrogen ions away while bases accept hydrogen ions. (Decelles, 2002).

My science fair topic will be measuring the acidic levels in different companies of water bottles such as Aquafina, Dasani, Evian, Fiji, Miami Dade Tap Water, Penta, Publix Spring Water, Smart Water, Smart Water, Volvic, Voss, and Zephyrhills. Bottled water has been tested for its ppm (parts per million) to measure the amount of particles inside the water. The pH scale is a measurement of how acidic or basic an aqueous solution is. The pH scale has a range of 0-14; numbers less than 7 are considered acidic and numbers greater than 7 are considered basic. An acidic pH level means that the solution has more free hydrogen ions, and a basic pH level means that the solution has more free hydroxyl ions. pH is reported in logarithmic units and an increase or decrease of one on the pH scale has a 10-fold change. The negative logarithmic of the hydrogen ion concentration calculates the pH level of a solution. This is why pH stands for the potential of hydrogen and it calculate din

On a logarithmic scale, each tick mark on the scale is the previous tick mark multiplied by some number” (mathisfun.com, 2015); because of this, each whole pH value below seven is ten times more and the same goes for pH values above seven. Adding water to any substance can make it more acidic or basic. Acidic is defined as the forming or yielding of acids (the free dictionary, 2015). Vinegar is acidic. When referring to science, basic is defined as “of or relating to a base, containing a base, especially in excess of acid and alkaline” (the free dictionary, 2015).
