An aqueous solution of Ca(OH)2with a concentration of 0.146 M was used to titrate 25.00 mL of aqueous HCl. 15.63 mL of the Ca(OH)2was required to reach the endpoint of the titration. How many moles of base were required to react completely with the acid in this reaction? How many moles of HCl were present in the original 25.00 mL of acid What is the molarity of the original HCl solution?

A 50.0 mL solution of Mg(OH)2 of unknown concentration is titrated with 0.348 M HCI. The equivalence point (end point) is reached after 62.8 mL of HCI were dispensed into the Mg(OH)2 solution. What is the molarity concentration of the base?

Chromic acid, H2CrO4, is used in ceramic glazes and colored glass, and is particularly effective for cleaning insoluble organic residues off laboratory glassware. A 10.0 mL sample of chromic acid solution contains 46.0 mg chromium (which is found in the chromic acid). What volume (in mL) of 0.0700 M KOH is needed to neutralize the 10.0 mL sample of chromic acid?

If 8.00 mL of a hydrochloric acid solution had a known concentration of 0.3456 M, how many mL of a 0.1773M NaOH solution would be required to reach the equivalence point?

A 4.80 mL sample of an H3PO4 solution of unknown concentration is titrated with a 1.100×10−2 M NaOH solution. A volume of 7.32 mL of the NaOH solution was required to reach the equivalence point. What is the concentration of the unknown H3PO4 solution?         Express your answer with the appropriate units.

An aqueous solution of Ca(OH)2with a concentration of 0.188 M was used to titrate 25.00 mL of aqueous HCl. 18.63 mL of the Ca(OH)2was required to reach the endpoint of the titration. How many moles of base were required to react completely with the acid in this reaction? How many moles of HCl were present in the original 25.00 mL of acid?

A titration was done using 32.83mL of a weak acid and 0.141 M NaOH. If 32.81 mL of the NaOH was required to reach the equivalence point, what was the initial concentration of the weak acid?

O SIMPLE REACTIONS Determining the molar mass of an acid by titration Jacque An analytical chemist weighs out 0.279 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with 0.1400M NaOH solution. When the titration reaches the equivalence point, the chemist finds he has added 33.8 mL of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. mol fo Exnation Check |Privecy 2021 McGraw-Hill Education. All Rights Reserved. Terms of Use MacBook Air
