How Does Diet Affect the pH of a Body?

What were your controls for this experiment? What did they demonstrate? Why was saliva included in this experiment?

PH can affect the way fermentation occurs due to the irregularity of the acidity or alkalinity within the glucose concentration. The aim of this experiment is to determine how pH affects the yeast fermentation rate by performing the experiment numerous times with a different pH in the glucose solution. My hypothesis states that ‘If the pH is lower than the neutral point then the fermentation reaction will occur faster?’ To set this experiment I had to make adjustments to the original practical method in order to fit the new practical, which depended on the question that was chosen.

Before beginning, I will measure the pH levels of each of my controlled independent variables: Lemon juice, 20% sodium bicarbonate mixture (with water), and water. This is to verify each substances pH level before the main experiment. I will use the 100ml plastic beaker to do this, measuring out 10ml of each of the three substances, and using 3 pH strips to get an accurate reading for each of them.

The readings would be more accurate if the mixtures were done multiple times, then you would be able to calculate an average. To further test this hypothesis, an actual human liver could be tested in the same way to see what pH level it functions best at. If the same results occurred, then it could be the basis for further research into enzyme function in

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.

Our bodies work in incredible and various ways. Especially when our body is affected by imbalances in our pH. PH is the concentration of hydrogen ions in the blood. Solutions with a high concentration of H+ have a low pH, unlike solutions with a low concentration of H+ have a high pH. The normal pH is between 7.35-7.45. Anything else that ranges either below 7.35 or above 7.45 is abnormal. With this being said, the pH tells you whether the person is in acidosis (pH < 7.35) or alkalosis (pH > 7.45). If the human body is too acidic/alakalitic, the body must expend energy to compensate for this; energy that would be better served in other areas of the body. This is known as homeostasis, a characteristic system that regulates its internal environment and tends to keep things constant. A good way of sustaining pH homeostasis is through a short term mechanism called chemical buffer system, which are bicarbonate, phosphate, and protein buffer systems. Buffer systems solution resists changes to its pH when a strong acid or base is added. Another system that manages severe changes of pH is the

The initial goal of this experiment was to investigate the properties of an unknown acid or base. These properties include pH, concentration, and how the solution behaves once titrated. In order to accomplish these goals, the initial pH of the unknown compound needed to be found through the use of pH strips and/or a PASCO probe. It was also necessary to titrate the unknown compound to find the equivalence point, which would allow the calculation of the initial concentration of the unknown chemicals. In order to see how dilution affected the pH of the unknown compound, it was necessary to dilute the unknown compounds over a series of steps and observe the trend. Finally, it was helpful to test the household chemicals for their acidic or basic properties and compare how they reacted to the reactions of the unknown compounds.

The normal blood pH varies between 7.35 and 7.45. Kidneys, lungs and chemical systems known as buffers are responsible for the regulation of the homeostasis of acid-base balance. In case of a rise in blood pH, the buffers release hydrogen ions, and bind the hydrogen ions when the pH drops. The carbonic acid-bicarbonate system is one of the major buffer systems. Carbonic acid is known to dissociate reversibly, releasing protons and bicarbonate ions. When there is a rise or drop in blood pH, ions are added to or removed from the blood. A rise in the blood pH would mean that there is additional of a strong base in the blood, making it more alkaline as more carbonic acid is forced to dissociate On the other hand, a drop in the blood’s pH level means that there is more acid in the blood. The bicarbonate ions here begin to bind with protons. It can be noted from both cases that in the absence of the buffering system, changes in blood pH would be much

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

In the morning the pH of urine ranges from 6.5 - 7.0, which is close to or is neutral. The body uses overnight rest to excrete excess acids, the capacity varies base on toxin load (Nall, 2012). Ones urine is higher in the evening (pH= 7.5-8.0) primarily because no beverages or food is consumed when sleeping. Unknown urine 1, and 3 had a generally average urine pH level. Unknown 2 and 4 had a relatively low pH (roughly 6.0). A low pH could be caused by dehydration, diabetic ketoadosis, or starvation (Nall, 2012). The low pH also signal that the bodies fluids are much to acidic. The body then has to work harder to keep it safe by releasing excess amounts of electrolytes (Nall, 2012). Unknown 2 and 4 should eat more citrus fruits (oranges, grapefruit, or lemons) to raise the pH or their

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

1. During my experiment, as my lab partner and I added more sodium hydroxide, the pH level began to rise. As the pH level climbed, the solution began to have more precipitate. In the stomach the pH level is 2.

In this presentation we will discuss the irreversible effect of acid on Enamel dissolution known as EROSION. Types of acid in the mouth has gastric origin (refluxes, regurgitation), dietary origin (food and drinks), and environmental origin (chlorinated swimming pools, industrial).

The alkaline diet has been proven to help normalize the body and promote optimal health. If you are just starting out with an alkaline diet, it is better to ease your body into the process. Dr Robert Young has developed a wide range of products that help your body adjust to and be able to easily absorb alkaline-based products.

The purpose of this food journal was to view my eating habits because the basic average
