Practice Exercise 15.7 A 50.0 mL sample of HCl required 24.81 mL of 0.1250 M NaOH for neutralization. What is the molarity of the acid? MHCI the tolerance is +/-2% Paired Exercise 15.27 Given the data for the following separate titrations, calculate the molarity of the HCI: mL HCI Molarity HCI ml NaOH Molarity NaOH (a) 42.1 38.4 0.654 M IM (b) 17.1 33.7 0.325 M M (c) 32.0 13.4 M 0.412 M Paired Exercise 15.33 Determine how many milliliters of 0.225 M HCIO, will be required to neutralize 35.12 g Ca(OH)2 according to the reaction: 2 HCIO (aq) + Ca(OH)>(s) - Ca(CIO),(aq) + 2 H2O(1) ml x 10
