Question

what is ph value?explain​

Answer 1

Explanation:

pH is defined as the negative logarithm of H+ ion concentration. Hence the meaning of the name pH is justified as the power of hydrogen.. To determine the strength of acids and bases quantitatively, we use a universal indicator which shows different colours at different concentration of hydrogen ion in solution.

Answer 2

Answer:

step by step explanation

Explanation:

ph scale is a scale which is used for measuring the power of hydrogen ion in a solution

if ph is below 7 then the nature of the solution is

Acidic. but 0-3 is strong acids and from 4-6 is weak acids.

if ph is above 7 then the nature of the solution is base.

but 7-11 is strong base and from 12-14 is strong bases.

ph 7 is neutral
