Answer 2

Hello dear,

● pH -
- pH is the negative logarithm to base 10 of molar concentration.
- It explains the acidity or basicity in aqueous solution.

● Answer -
pH = 13.6

● Explanation -
First we'll calculate pOH -
pOH = -log(0.4)
pOH = 0.4

pH is calculated using formula -
pH = pKw - pOH
pH = 14 - 0.4
pH = 13.6

Therefore, pH of 0.40 M ammonia soln is 13.6 .

Hope this helps you...
