(A) For a neutral solution,the concentration of hydrogen ions $[H^+]$ is equal to the concentration of hydroxide ions $[OH^-]$.Since $K_w = [H^+][OH^-]$,for a neutral solution,$K_w = [H^+]^2$.Taking the negative logarithm on both sides,we get $pK_w = 2pH$.Given $pK_w = 13.36$,therefore $pH = \frac{13.36}{2} = 6.68$.
