The pH at equivalence point during a titration of a weak base with a strong acid would be ○ acidic ○ basic neutral

Concentration of HCl: 0.05 M Volume of HCl: 4.4 ml Concentration of NaOH: 0.0088M Volume of NaOH: 25 ml

When 30 .00 mL of 0.1011 M HCl in 50 mL of deionized water is titrated against 0.09889 M NaOH, the pH increases. What is the volume (in mL) of NaOH required to reach the equivalence point and a pH of 7.00? Find the pH when the volume of NaOH added is 0.02 mL less than the volume required to reach the equivalence point. Find the pH when the volume of NaOH added is 0.01 mL less than the volume required to reach the equivalence point. Find the pH when the volume of NaOH added is 0.02 mL more than the volume required to reach the equivalence point. Comment on the significance of the changes in pH values in relation to the increments of sodium hydroxide added when going “through” the end point. Define equivalence point. For a weak base/strong acid titration, is the pH at the equivalence point <, >, or equal to 7?

Which of the following aqueous solutions are good buffer systems? 0.28 M perchloric acid + 0.19 M sodium perchlorate 0.38 M sodium perchlorate + 0.29 M barium perchlorate 0.16 M potassium hydroxide + 0.20 M potassium chloride 0.30 M ammonia + 0.35 M sodium hydroxide 0.15 M acetic acid + 0.12 M sodium acetate
