Solution

For basic buffer
$pOH space equals space pK subscript straight b space plus space log space fraction numerator left square bracket salt right square bracket over denominator left square bracket base right square bracket end fraction ii right parenthesis thin space pH space plus pOH space equals space 14 Given comma space straight K subscript straight b space equals space 1 space straight x space 10 to the power of negative 10 end exponent. space left square bracket salt right square bracket space equals space left square bracket base right square bracket pOH space equals space minus space log space straight K subscript straight b space plus space log space fraction numerator left square bracket salt right square bracket over denominator left square bracket base right square bracket end fraction pOH space equals space minus space log space left parenthesis 1 space straight x space 10 to the power of negative 10 end exponent right parenthesis space plus space log space 1 equals space 10 pH space plus space pOH space equals space 14 pH space equals space 14 minus 10 space equals space 4$
