Research on the Effects of Various Beverages on the pH of Saliva

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”.

Introduction: The concentration of Hydrogen Ions in a substance is its pH. Hydrogen Ions (H+), and Hydroxide Ions (OH-) are formed when an electron jumps from one H2O atom to another. When a Hydrogen Ion is in an aqueous solution (a solutions with water as the solvent) it bond with an H2O atom creating H3O also known as Hydronium. A substance with more Hydrogen Ions than Hydroxide Ion is called a base. A substance with more Hydroxide Ions than Hydrogen Ions is called an acid. This can be seen on the pH scale below (Figure 1). A pH scale shows the number of Hydrogen

For my science fair project I chose to measure the pH in three different common drinks, so people could find out what they were drinking on a day to day basis. The pH scale works like this: the lower the number the more acidic it is. The higher the number the more alkaline it has in it. The scale stretches from 0-14, with 14 being very basic, 0 being very acidic, and 7 being neutral, like water.

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

Introduction The inspiration for this experiment came from a book called Counting by Sevens by Holly Sloan. The main character in the book has a garden and she regularly checks the pH value of the soil in her garden. From this came the idea to do this science fair experiment on pH values. Through the years people have found out the different ideal soil pH values of plants, herbs, vegetables, as well as the pH value of cow’s milk and blood.

In experiment 3 drinking water quality, I will test the quality of two different types of bottled water and tap water using materials such as: Dansani bottled water, Fiji bottled water, ammonia test strips, chloride test strips, 4 in 1 test strips, phosphate test strips, iron test strips, (3) 250ml. beakers, parafilm, pipettes, (3) foil packets of reducing powder, stopwatch, permanent marker and water. First you must label the (3) 250ml. beakers with Tap water, Dasani, and Fiji, and pour 100ml of each type of water into the beakers name. Next place an ammonia test strip with the pads down into the tap water and move it up and down for 30 seconds. Next remove the test strip shaking off excess water and then hold level with pad side up for 30 seconds. Read the results of the strip pads by

The content of these tubes was then later transferred to separate small labeled beakers. The initial pH of the water in test tube A was then measured and recorded using a pH meter. Next. One drop and 1 mL of 0.1 M HCl was added to the water in test tube A, and the pH was measured and recorded. The pH meter was rinsed off each time it was used with distilled water and blotted dry. The initial pH of test tube B was then measured and recorded. Using a graduated cylinder and a pipette, 1 mL of 0.1 M HCl was added to the buffer in test tube B, and the pH was measured and recorded. Then, an additional 2 mL of 0.1 M HCl was added to test tube B, and the pH was measured and recorded again. After adding those 2 mL, three more millimeters of 0.1 M HCl

7. What is pH? PH is a way to measure the concentration hydrogen ions in a sample. The pH scale is ranged from 0 to 14. PH is always thought of measuring the activity of hydrogen ions.

Young individuals especially students are told repeatedly that exercise is the key to a healthy lifestyle. However, one must keep in mind that strenuous exercise depletes fluids and minerals in order to ensure a stable homeostasis. The minerals your body loses through sweat are called electrolytes. An electrolyte is defined as any substance that will separate into ions when in a solution. These fluids and minerals must be replenished through the consumption of a beverage. In this experiment the researcher will determine whether various, popular sports drinks or fruit juices better replenish the lost electrolytes.

Experiment 5 titled “Acids, Bases, Salt, and pH”. The purpose of this lab is to become familiar with some properties of salt, bases, and acids, measure acidity (pH), and correlate abnormal acidity of blood or urine. The activities for this lab is to measure the pH of some acid solutions and base solutions using pH paper/meter, and neutralize an acid solution by reacting with base solutions. To begin this experiment (Acid), there will be bottles of different acids (hydrochloric, nitric acid, sulfuric, and acetic acids) on top of the bench. Place one drop of each acid on a blue and red litmus paper and then place a drop of each liquid on (pH) paper. Record the observations. For the Base, place one drop of each liquid (sodium hydroxide, ammonium

The method I used in the experiment was followed by the lab manual of “Fundamentals of Life Science by Brenda Leady” (Leady 2017). We conducted an experiment of 8 different tests, 4 of the different classifications of pH, and 4 different

In an introductory chemistry course (such as GCSE), whenever you have talked about hydrogen ions (for example in acids), you have actually been talking about the hydroxonium ion. A raw hydrogen ion is simply a proton, and is far too reactive to exist on its own in a test tube.

I also learned that pH scale is measured either with litmus paper, you dip in the substance and measure that color to a acidity color

Alkaline water is a better option because what many people do not realize is that vegetables and fruits are not enough to even out their pH levels. This is the case for those who eat fewer vegetables and fruits and more meat and other acidic foods. To ensure a healthy body with even pH levels, it is best to drink not only healthy water but alkaline water as well to help even out the acid and

To study the effects of energy drinks in the human body, a particular group of researchers at Mayo Clinic in Rochester, Minnesota decided to test a commonly known energy drink called Rockstar. Once tested, they observed that, “In just 30 minutes, one can of Rockstar boosts blood pressure and causes a fight-or-flight hormone to rise and affect the cardiovascular system.” (Times). For the research, scientists worked with 25 participants, 11 females and 14 males whom chugged down a 16- ounce can of the brand Rockstar on an empty stomach in five minutes or less. All of the participants were an average age of 29, and were healthy with a body mass index of approximately 25 which means they were right on the border of normal weight and overweight,
