3. What is the N of an HCl solution if 45.23 ml of it is required to titrate a 0.2505 sample of N32CO3? 4. A sample of soda ash (impure Na,CO3) is titrated with 0.5000 N H2SO4. If the sample weighs 1.1000 g and requires 35.00 mL of the acid for complete neutralization, what is the %Na¿CO; in the ash assuming no other active component is present?

Kindly answer 3 and 4 please! Thank you

MODULE 8 ACTIVITY 2 INDIVIDUAL ACTIVITY ON ANACHEM LEC PROBLEMS ON VOLUMETRIC ANALYSIS Instruction: After studying the ppt on Volumetric Analysis and Module 8 answer the ff problems. Use the following formula: 3. %analyte = Ntrant X_Vitrant X EqWt Analyte x 100% wt. of sample 1. GV1 = CV2 2. Nacid x Vacid = Noase x Vbase Problems: 1. What volume of 0.2963 N H,SO, is required to prepare 250. 0 ml of 0.1000 N H;SO4? 2. What is the N of an HCl solution if 25.03 mL of it requires 29.07 ml of 0.1025 N NaOH for titration? 3. What is the N of an HCl solution if 45.23 ml of it is required to titrate a 0.2505 sample of Na;CO;? 4. A sample of soda ash (impure Na,CO3) is titrated with 0.5000 N H,SO4. If the sample weighs 1.1000 g and requires 35.00 ml of the acid for complete neutralization, what is the %Na,CO; in the ash assuming no other active component is present? At. Mass: CI 35.45 Ag 107.9 P 30.97 O 16.00 Fe 55.85 Mg 24.31 C 12.01 Al 26.98 Na 22.99 Volumetric Analysis . Show your solution in the appropriate box. For each problem, give the derived formula, substitute the given in the formula and write the final answer on the last column with proper unit & correct no. of SF. Derived Formula Substitute the given in the formula Final answer 1. 3. 4. 2.
