What is pH? It is a very important part of any biology book. This term defines what the pH level is. It is very important to understand why and how pH levels are important in biology.
Definition. pH is the concentration of alkaline or acidic ion content in a solution or in the whole human body. Therefore the literal meaning of the word pH is the power of water. Everybody knows that all the bases and acids don’t react with the same compound at the same temperature.
Most solutions have both high and low pH levels. The concentration of alkaline or acid in any solution is equal to the pH. The concentration of a solution is also equal to the concentration of the hydrogen ion in the solution. The lower the pH of the solution, the more stable it is, but the higher the concentrations of acid and base substances.
The term logarithmic can be defined by taking the logarithms of the pH concentrations. pH can be measured using pH test strips. The pH of a solution is a measure of its aconitivities, or of its electrical conductivity, or of its dissimilarity to an ideal solution. The logarithms of the pH are termed positive, negative or average pH.
The test results are termed as pH level. A possible reason of why pH level is used here is because it is a physical measurement of the concentration of hydrogen or hydroxyl ions in a solution. These ions can be thought of as being solid solutions. Water has a positive ion concentration, H20, while polar solvents like oil, fats and many organic solvents have a negative ion concentration, P-values. Water’s pH level is considered to be in the range between zero (pH of tap water) and one (pH of your toothpaste). It is important to remember that your toothpaste does not have pH; it may vary according to how you use it and whether it is alkaline or acidic.
When a solution is placed on a pH scale, the pH changes from zero to one, two, three and so on, where higher numbers mean harder, more acidic solutions. Many people confuse pH with the molarity of water. However, there is a huge difference between the stability of a solution on the pH scale and its stability at any temperature. Your body can change its pH on its own, but solutions on the pH scale are easier to measure and therefore are more widely used in laboratory testing and experiments.
The common use of pH indicator is to determine the concentration of pH in aqueous solutions. For example, if you want to test whether or not you are allergic to grass allergen, you will need to check the pH level of your stool. A pH indicator will show you the pH of your aqueous solutions. Other uses of the pH indicator are for industrial purposes such as in the production of antifreeze, ink, pesticides, fertilizers and pharmaceutical drugs. The pH indicator in these products help to keep the concentration of the different ingredients constant.
pH indicator in home applications include testing the acidity or alkalinity of your urine, skin and eyes. It is essential to know the exact pH range of your body fluids to prevent dangerous imbalance. There are two kinds of pH indicator based on surface tension and oral absorption. In the case of the oral absorption method, a thin plastic tube is inserted into the mouth and the sensor measured the amount of time the material spends in contact with the tongue. The surface tension indicator relies on the physical attraction of the probe to the tongue as it moves.
