Problem- calculate the solubility of khtar in three solvent, Ask an Expert

Academics

Problem- Calculate the solubility of KHTar in three solvent systems: pure water, 0.10 M KNO3, and 0.10 M NaNO3. The solubility of KHTar will be determined by titration of the HTar- with standard NaOH solution.

Molarity of NaOH = 0.107 M

Volume needed to titrate pure water = 10.2 mL

Volume needed to titrate 0.100 M NaNO3 = 14 mL

Volume needed to titrate 0.100 M KNO3= 5.5 mL

50 mL of solution was used for each titration

From this data calculate the solubility of KHTar (in moles per liter) for each of the three solvent systems. From the measured solubilities in each of these solutions, calculate the Ksp.
