The hydrogen ion concentration of a solution is 1.0xx10^(-9) m.What is the pH of the solution ?Find out whether the given solution is acidic .basic or neutral .

Answer»

Solution :PH=`-log_(10)[H^(+)]`
pH+`-log_(10)(1.0xx10^(-9))`
pH=log 1-`log 1xx10^(-9)`
=0.0000-9.0000
pH=9
pH `GT` 7,so the solution is basic.
