What is the molar mass of an unknown triprotic acid if 0.0913 g of the acid is titrated, and the first equivalence volume is reached after having delivered 19.32 mL of a 0.1000 M KOH solution? Group of answer choices 94.5 g/mol 47.3 g/mol 142 g/mol 21.2 g/mol 15.8 g/mol

A 0.658 g sample of a diprotic acid is dissolved in water and titrated with 0.130 M NAOH. What is the molar mass of the acid if 38.4 mL of the NaOH solution is required to neutralize the sample? Assume the volume of NaOH corresponds to the second equivalence point. 10 11 12 13 molar mass: g/mol 18 19 20 21 22 23 24

Consider the titration of an acetic acid (CH3COOH) with sodium Hydroxide  to form sodium acetate (NaCH3COO) and water. A 10.0 ML sample of acetic acid requires 37.55 ML of 0.233 M NaOH to reach the equivalence point. The amphiprotic substance is acting as :  Neutral an acid Or a base

Which of the following is true of a buffer solution? Buffer solutions must have a pH over 11.0. Buffers resist changes to their pH. O Buffer solutions do not react with acids or bases. Buffers must have a pH under 4.0. Buffer solutions must have a strong color.
