In a titration of 42.0 mL of a 0.500 M solution of a diprotic acid H:CH2O4 (malonic acid) with 0.255 M NaOH, how many grams of NaOH are required to reach the second equivalence point? (MW_NaOH= 39.997 g/mol) 2-In the titration of 15.0 mL of 0.400 M HCOOH with 0.150 MLIOH, how many mL of LiOH are required to reach the halfway point? 3-A 25.0 mL solution of HNO: is neutralized with 21.6 mL of 0.250 M Ba(OH)2. What is the concentration of the original HNO3 solution? 4-A student performs a titration of 30.0 mL of a phosphoric acid (H3PO4) solution of unknown concentration with a standardized 1.25 M NaOH solution. The titration requires 26.2 mL of base to reach the third equivalence point. What is the concentration of the H3PO4 solution? 5-How many milliliters of 0.20 M HC1 is required to neutralize 40.0 mL of 0.80 M NaOH? 6-What is the pH of a 0.340 M solution of Ca(NO2)2 (Ka of HNO: is 4.5 × 10-)? 7-What is the percent ionization of H:NNH: in a solution with a concentration of a 0.430 M? (Kb 1.3 x 10-) 8-An unknown weak acid with a concentration of 0.290 M has a pH of 5.600. What is the Ka of the weak acid?
