Water is added to a test-tube containing dilute NaOH of pH 11. What could be the pH of the resulting solution?

NaOH atomic mass is 39.977

pH is 11 due to dilution must be multiplied by 0.11 to find pH

39.977 x 0.11 = 0.43979 x 100%

43% pH

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
