11. Which of the following statements is true? a) Hydrophobic bonds are strong over large distances. b) Water molecules can act as bases. c) In pure water (at 25 ) the concentration of H3O+ is slightly more than the concentration of OH-. d) In acidic solutions, the concentration of OH-exceeds the concentration of H3O+. e) In solutions with pH greater than 7, the concentration of H3O+ exceeds the concentration of OH-. Solution B) Water molecules can act as bases. Infact water molecules are neutral in nature at pure state. their have equal positive and negative charge because to oh- and h30+. Due this it can accept both charges and can become acidic and basic, depending on the solution has been added..
