Ph = - Log (Hcl)

= - Log (0.00750)

= 2.12

Ph = 2.12

Answer: pH = 2.12

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

[tex]pH=-\log [H^+][/tex]

[tex]pOH=-log{OH^-}[/tex]

[tex]pH+pOH=14[/tex]

Give :[tex][H^+][/tex] = 0.00750

[tex]pH=-log[0.00750][/tex]

[tex]pH=2.12[/tex]
