How Does Soil Affect The Ph Of Water?

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.

Purpose/Hypothesis: The purpose of this experiment is to use both cabbage juice and pH paper to determine the pH of household items. This way, we can tell which products are basic and which one are acidic. If we use cabbage juice as an universal pH indicator by comparing it to pH paper then pH determined by the cabbage juice will be unstable because by using cabbage juice, it can be different depending on how diluted it is.

The pH scale is 1 to 14, 7 being the best quality. To the right is a pH scale. 7 is what the water should be. 7 is also what we had for the creek average. We had a higher number of rocks neutralizing acid (limestone is the stone found mostly in the creek) than the ones that don’t. this means that the acid rain we get is mostly neutralized by limestone in the stream. We get acid rain from Philadelphia. This is because of the massive steel companies. All of the toxic smoke comes over and comes down in the conodoguinet as acid rain. So the creek is non-acidic and non-alkaline.

Acidity of an ecosystem, measured in pH, is a crucial factor to the survival of a species in an ecosystem. Altering it can have result in dramatically negative effects, in spite of the fact that pH of an ecosystem has been dramatically changed over a relatively short period of time due to various human activities. For example, acid rain is a major environmental problem that is caused by human-made pollution. When fossil fuels are burnt to get energy, pollutants like sulfur dioxide and nitrogen oxides get mixed into the rainwater and eventually are evaporated into the atmosphere. These gases enter the atmosphere, and mix with water in the water cycle to form an acidic mixture of water and gases. This water falls in the form of acid rain, which

“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

I will measure the soil PH in 5 different places to get an accurate and reliable results.

To start out this study the difference between acids and bases has to be identified. Acids have very low pHs and have a high concentration of hydronium ions, while bases have a high pH and have a high concentration of hydroxide ions. The difference between strong bases and acids, and weak bases and acids is the amount of dissociation. Strong bases and acids dissociate a large amount and let go of their ions in solution, while weak bases and acids may only let go of some of their ions. This is important because if the unknown solutions aren’t strong acids or bases then using their ions to calculate the pH of the solutions will give false results (Diffen 2012).

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;

Each person got to test either the phosphates, nitrates, dissolved oxygen, or the ph in the creek. Phosphates and nitrates are nutrients found in water due to fertilizers, decaying plants and bacteria. Dissolved oxygen is the amount of gaseous oxygen dissolved in the water. As we recorded our results, we discovered that the dissolved oxygen levels were very high, which is good because the higher amount of dissolved oxygen in the water, the healthier the creek is. The phosphates levels in the creek were all perfect zeros, which is great because having nutrients in the creek is not healthy. The nitrate levels were slightly higher, at 0.9. That is not bad at all, but it isn’t perfect, showing signs of pollution. The ph levels in the rocks were neutral, right at seven. If they were lower than 7, that would mean they have acids in them, and if they were higher than 7, they would have alkaline in them. Alkaline, or bases, neutralizes acids. The number of rocks that we found that neutralized acid was 65, and the number of rocks that did not neutralize acids were 29. This shows that about one-third of the rocks in the creek do not neutralize acids.

What types of organisms are found in soil? Determine the relationship between soil and organisms.

The pH of soil is important for the absorption of nutrients into the plant. Of the 17 needed plant nutrients 14 of them are acquired through the soil. Acidity is needed to break down and dissolve these nutrients. The nutrients are able to dissolve into the soil faster when the acid is acting as a solute. Another way the pH affects the soil is by influencing microorganisms. The bacteria is crucial in the growth and development of the plant, the bacteria’s role is to break down and decompose organic matter in the soil. If the pH of the soil is too high the acid will slow down and eventually stop the microorganisms. Most plants ideal pH is between 6-7, slightly acidic. Many plants are outliers and thrive in pH such as carrots and corn, which can withstand pH as low as 5.5. If the pH of the soil is too high for the desired crop farmers can add material such as limestone, and wood ashes to raise the pH to the desired level. The pH of the soil can also be changed naturally through the leaching of calcium, magnesium and sodium by rainwater. Carbon dioxide from rotting organic matter can also increase the pH of the soil. Acids can also be created organically in the form of sulfuric and nitric

At this station, we tested the creek water for phosphates, nitrates, and dissolved oxygen. What we found for phosphates was an average of 0.3 phosphates. For nitrates, we found an average of 0.8 nitrates. For the dissolved oxygen, we got an average of 11.4. This shows that the Conodoguinet Creek is pretty healthy. We also tested for acidity and alkalinity. To do this, we needed to use a pH scale. A pH scale goes from 0 (acidic) to 14 (alkaline). A good place for the water to be is 7, this means that the water is not acidic, nor has alkaline in it, but it is neutral. The water in the Conodoguinet Creek was at 7, so it was

Soil acidity/alkalinity is essential for farmers determining the profitability of planting certain types of crop in certain areas. Some plants grow well in slightly acidic soils while others prefer an alkaline environment.

Saline environments tend to hinder agricultural production by lowering crop yields, often quite substantially. The traditional response to the threat of salinity-induced crop yield reductions is to apply water in excess of plant requirements so as to leach the salts out of the root zone. (Letey and Dinar, 1986).

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
