what is ph value?????
Answers
Answer:
In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
Explanation:
- Elements -
→ The 'H' in pH stands for the element, hydrogen. On a simple level, the pH scale can be thought of as a ranking of the amount of hydrogen ions in a solution: the more hydrogen ions, the lower the pH number.
- Si unit
→ pH is a logarithm (the negative of the logarithm of H+ activity), and as such it has no unit. It may be ralative conc. of solute.
- Basics
→ pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
- Formula
→ pH is defined by the following equation, pH = −log [H+] , where [H+] denotes the molar hydrogen ion concentration. Notice that we are required to take the common (base 10) logarithm of the hydrogen ion concentration in order to calculate pH.
Answer:
PH is a measure of how acid and base water is.
the range goes from 0 to 14 with 7 being natural.
phs less than 7 indicate acidity. and pHs great than 7 indicates base.
The ph of the water is a very measurement concerning water quality.
