Calculation of Normality! Please help fill the empty boxes showing your calculations!
Normality-9rams solutc pr Litcrs of Solutc only conuentrahon unit 40 theoretical Data Table Trial 1 D. 00lg Mass KHP M wt KHP-204.23 g/mol equiv, wt KHP 204.23 gleg .0029 equiv KHP- mass KHPub equiv NaOH-S NAQH Initial buret reading Final buret reading Volume of NaOH used .0029 equir KHIP- eq wt KHP 2423 49 0mL NMn Normality of NaOH Ave. Normality of NaOH 9.4 Procedure: Part II unknown Acid ( 1. Fill the buret with the now standardized NaOH (secondary standard). 2. Pour 25.0 mL of the unknown acid 1 or 2 into the Erlenmeyer flask and add 2-3 drops to it. 3. Titrate as usual to the end point 4. Calculate the concentration of the unknown acid 5. Repeat the procedure two more times and average the normalities of the unknown acid. 6. Calculate the % error using the theoretical value obtained from the instructor 7. Note: NaVa NV Data Trial 0,00 ml 0.00mL Initial buret reading Final buret reading Volume of NaOH Volume of Unknown Acid HCl Normality of Unknown Acid L.
