Question

The concentration of [OH-] ions in a solution is 1×10^−12 Mole per litre. What is the pH of the solution?​

Answer 1

$\huge\color{pink}{\mathfrak{ᴀɴsᴡᴇʀ}}$

The hydroxide ipn concentration

$\sf[OH]² = 1.0 \times {10}^{ - 8} M$

$\sf \: p OH = - log{[OH}^{ - }]$

$\sf= - log1.0 \times {10}^{ - 8} = 8$

$\sf \: pH = 14 - pOH \\ 14 - 8 = 6$

So the ph of the solution is 6
