At certain temperature `K_(w)` for water `4xx10^(-14)` which of the following is incorrect for pure water at the given temperature? `log 2=0.3`A. `pH=6.7` and water is acidicB. `pH=6.7` and water is neutralC. `pOH=6.7` and water is neutralD. `pH+pOH=13.4` |

Answer» Correct Answer - A `[H^(+)][OH^(-)]=K_(w)=4xx10^(-14)` In pure water `[H^(+)]=[OH^(-)]` `:. [H^(+)]=2xx10^(-7)` or `pH=7-log2=7-0.3=6.7=pOH` pure water is neutral. |
