1) 43.9 mL of 1.19 M perchloric acid is added to 48.5 mL of sodium hydroxide, and the resulting solution is found to be acidic. 24.2 mL of 0.541 M barium hydroxide is required to reach neutrality. What is the molarity of the original sodium hydroxide solution? 2) 56.3 mL of 1.35 M hydroiodic acid is added to 43.6 mL of calcium hydroxide, and the resulting solution is found to be acidic. 15.6 mL of 2.03 M sodium hydroxide is...
A 4.36 g sample of an unknown alkali metal hydroxide is dissolved in 100.0 mL of...
A 4.36 g sample of an unknown alkali metal hydroxide is dissolved in 100.0 mL of water. An acid-base indicator is added, and the resulting solution is titrated with 2.50 M solution of HCl. The indicator changes colour, signalling that the equivalence point has been reached after 17.0 mL of the hydrochloric acid solution has been added. Determine the molality of this alkali metal hydroxide solution and What is the mass percentage of the metal hydroxide in the solution? Determine...
