Jun 13, 2019 · An acid should have a pH much less than seven usually one to three and a base should have a high pH value usually around 11 to 13. While it's theoretically possible to calculate a negative pH, pH values should be between 0 and 14 in practice. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7, such as pure water is neutral. A pH less than 7 is acidic and greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times 10 x 10 more acidic than a pH of 6. The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14. It's a lot easier to use a logarithmic scale instead of always having to write down all those zeros! By the way, notice how one hundred million million is a one with fourteen zeros after it? What is the maximum value of pH encountered in the groundwater deep or shallow? I want to check the variation of pH in the groundwater of different locations and reasons of variations.

The higher the pH reading, the more alkaline and oxygen rich the fluid is. The lower the pH reading, the more acidic and oxygen deprived the fluid is. The pH range is from 0 to 14, with 7.0 being neutral. Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. The minimum value is 0 and the maximum is 14, i.e the pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The indicator for acidity and alkalinity is known as the pH value. A pH value of 7 means a substance is neutral. The lower value indicates acidity, and a higher value is a sign of alkalinity.

When the pH is above 7.0, the water is alkaline, or basic there are more hydroxide ions than hydrogen ions. Since the scale is logarithmic, a drop in the pH by 1.0 unit is equivalent to a 10-fold increase in acidity. So, a water sample with a pH of 5.0 is 10 times as acidic as one with a pH of 6.0, and pH 4.0 is 100 times as acidic as pH 6.0. pH Values of Common Foods and Ingredients N. o. te: Variation exists between varieties, condition of growing and processing methods. Item Approx. pH Item Approx. pH. Anon. 1962. pH values of food products. Food Eng. 343: 98-99. Bridges, M. A., and Mattice, M.R. 1939. Over two thousand estimations of the pH of representative. Beyond this equivalence point, the story is much the same as in the strong-acid case. Addition of even a drop 0.05cm 3 of excess base raises the OH – concentration to 10 –4 mol dm –3 and the pH to 10. Of the three indicators which could be used in the titration of HCl, only one is useful for acetic acid. Apr 30, 2018 · The pH scale measures how acidic or alkaline basic a substance is. The scale runs from 0 to 14, where 7 is neutral. Any pH value below 7 is acidic, and any pH value above 7 is basic, with each whole number on the scale representing a tenfold increase or decrease in acidity.
