(acid) and HPO (base) d) HPO. (acid) and H.PO. (base) e) impossible to determine The following choice identifies a complete dissociation/ionization in water: 14. (1) strong bases (II) weak bases (III)strong acids (IV)weak acids d) a. b. C. I only I and II II and IV I, II, III and IV I and III 15. Which statement is not true of pH: a. a pH of 11 is 100 times more basic than a pH of 9 b. a pH of 6 is 1000 times more acidic than a pH of 3 as the pH value increases beyond a pH of 7, there will be more OH ions than H.O ions d. a pH value that is less than 7 is acidic none of these C. e. 16. a. Which one of these groups consists of soluble materials only: LiBr, NaNOs, Cacos d) (NH4)2CO3, K3PO4, NaOH b. ZnSO4, MgCO3, Al2S. none of these C. Mg(NO3)2, Cas(PO4)2, Agl 17. a. As the temperature of a solution increases the solubility of salts and the solubility of gases decreases, increases d) increases, decreases b. decreases, decreases doesn't change, doesn't change increases, increases c. 18. a. If the concentration of acid in a solution is increased, the: [HO] increases and pH decreases b. [HO] decreases and pH increases [HO] and pH both increase d. [HO] and pH both decrease (OH) increases and pH increases c e
