If 27.1 mL of base are required to neutralize 21.6 mL of the acid, what is the molarity of the perchloric acid solution M perchloric acid Submit Answer Try Another Version 1 item attempt remaining

Answer 1

Perchloric acid has one atom. ionizable Hydrogen I to Titrant is calon) 22922 04 Phd 07/2012 643 = Hclou M a ts Analyte is HCLOG Ca(4004), caq) + H2O 2H Cd Of Cag) + Ca(OH), coq! to 2 moles of Hlo acid would be required neutralize 1 mole of Ca (OH). Hence, for neutralization, moles of Hedda = 2 x moles of Ca (OH) . moles o Molasit - moles Volume Cindd » Sheloo 7 x 21.6 xlors =2x 0.199 m x 27. 1 x ios - 2x0.199 x 27.1 = 0.499 M [helog] = ³ 21.6 Hence, molarity of peschloric acid solution = 0.499m
