K_w=1xx10^(-14) calculate the concentration of [H_3O^+] in 10^(-8)M HC

1.	K_w=1xx10^(-14) calculate the concentration of [H_3O^+] in 10^(-8)M HCl.
Answer» `1.0xx10^(-8)` M `1.0525xx10^(-7)` M `1.0xx10^(-6)` M `9.525xx10^(-8)`M Solution :`[HCl]=[H_3^+ O]= 1xx10^(-8)` M `10^(-8) M LT 1 xx 10^(-7)M` of `H_3O^+` `THEREFORE` Total `[H_3O^+]=(1xx10^(-8)+1xx10^(-7))` `=1.1xx10^(-7) approx 1.0525xx10^(-7)` M `[H^+][OH^-]=10^(-14)` `therefore (10^(-8)+X)x=10^(-14)=0` `therefore x=9.5xx10^(-8)` Total `[H^+]=1xx10^(-8)+9.5xx10^(-8)` `=1.05xx10^7` M
