The pH of the solution obtained by mixing 2ml hcl with pH=2 and 3ml KOH with pH =12 is 11.6
Explanation:
pH is the measure of acidity or alkalinity of a solution.
Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.
To calculate the for HCl
Moles of ion =
To calculate the for KOH
pH+pOH = 14
pOH=14-12= 2
Moles of ion =
The chemical equation for the reaction of NaOH with sulfuric acid follows:
For neutralization:
1 mole of ion will react with 1 mole of ion
mole of ion will react with mole of ion
Thus = moles of KOH are left in 0.005 L of solution
