Hy everyone pl answer me

how to calculate pH?

Answer 1

Answer:

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

Answer 2

Answer:

pH of an aqueous solution represented as, $pH = -log[H^{+}]$ ,where $[H^{+} ]$ is the hydrogen ion concentration.

Explanation:

• pH is the negative logarithm of hydrogen ion concentration. pH value gives an idea about whether the chemical solution is acidic or basic.
• pH scale shows from a value of 0 to 14. The value 7 is considered neutral ,less than 7 is acidic in nature and greater than 7 is basic in nature.
