6. Which of the following statements about a titration with a pH of 7 at equivalence point is FALSE? 1.The pH increases sharply near the equivalence point. 2. The solution formed at equivalence is neutral. 3.Phenolphthalein is a good indicator for this titration. 4.At equivalence, the addition of a small amount of acid or base has no effect on the pH of the solution. 5. All of the above statements are true. 7. While performing a titration in the laboratory, a student plotted a titration graph, the pH at equivalence point was 5.4. The graph plotted above belongs to the titration between 1.NaOH(aq) with CH3COOH (aq) 2.NH3 (aq) with CH3COOH (aq) 3.NH3(aq) with HI (aq) 4.NaOH(aq) with HCl (aq) 8. The conjugate base of an acid is the particle that remains when a proton is added from the acid. 1. True 2.False 9.What is the pH of a 0.22 mol/L solution of NaOH(aq)? 1. 0.66 2. 1.50 3. 13.34 4. 2.2 10.A small Ksp value indicates the compound is less soluble than a compound with a high value of Ksp. 1. True 2.False
