Answer 1

A) [H*] = 3.5x10-M According to the ionic product of water, 1.0x 10-14 3.5x10-3= 2.8x10-12 M pH = -log[H"]=-log(3.5x10-)= 2.46 Since pH is less than 7, the solution is acidic - - - - - - - - - - - - - - - - - - - B) [OH-] =3.8x10-'M According to the ionic product of water, 1.0x 10-14 10-7 = 2.6x10M pH = -log[H* ] = -log(2.6x 10-*)= 7.58 Since pH is more than 7, the solution is basic ------------------- - - - - - - - - - - C) [H+] = 1.8x10-ⓇM According to the ionic product of water, 1.0x10-14 18x10- 5.6x 10M pH = -log[H* ]=-log(5.6x10^)= 5.26 Since pH is less than 7, the solution is acidic ------------------------------------------ D) pH=7.15 ** )=10-5H = 10-7.15 = 7.1x10*M According to the ionic product of water, [ou] - # 1.0x 10-14 7.1x10= 1.4x10-7 M Since pH is more than 7, the solution is basic
