The hydroxide...

Question

The hydroxide ion concentration of a solution is $1.0 \times 10^{- 9}$ M. What is the pH of this solution? State whether the given solution is acidic, basic or neutral.

Open in App

Solution

pOH = $- l o g_{10} [O H^{-}]$

Therefore according to thegiven information given in the question,

pOH = $- l o g_{10} (1.0 \times 10^{- 9})$

pOH = 9

pH = 14 – pOH

pH = 14 – 9 = 5

As, pH <7, so , the solution is acidic in nature.
