​

Answer 1

Answer:

Normality Problems1.  What is the normality of the following?a. 0.1381 M NaOHb. 0.0521 M H3PO4c. 0.5781 g acid (eq wt = 187.3) in 250.0 mL of solutiond. 0.321 g sodium carbonate in 250.0 mL of solution2.  What is the molarity of the following?a. 0.3181 N HClb. 0.1115 N Sr(OH)2c. 0.4237 g of KHP (eq wt = 204.23) in 100.0 mL of solution3.  What is the equivalent weight of the following?a. C6H5COOH b. Na2CO3c. H3PO44. If 25.00 mL of citric acid solution is titrated with 28.12 mL of 0.1718 N KOH, what is the concentration of citric acid?  (hint: normality is a concentration unit!)5. If 31.87 mL of base is required in the standardization of 0/4258 g of KHP (eq wt = 204.23), what is the normality of the base?6. What is the normality of an acid if 21.18 mL were needed to titrate 0.1369 g Na2CO3?7. What is the equivalent weight of a base is 0.2131 g required 43.71 mL of 0.0132 N acid?8. What is the %acid (eq wt = 173.8) if 20.07 mL of 0.1100 N base were required to neutralize 0.7231 g of sample?Normality Answers 1a.  NmoleqXLmol1381.0111381.01b. NmoleqXLmol156.0130521.01c. N
