Answer the following questions about the solubility of AgCl(s). The value of Ksp for AgCl(s) is 1.8 × 10−10. Calculate the value of [Ag+] in a saturated solution of AgCl in distilled water. The concentration of Cl−(aq) in seawater is 0.54 M. Calculate the molar solubility of AgCl(s) in seawater. Explain why AgCl(s) is less soluble in seawater than in distilled water.

A chemistry graduate student is given 500. mL of a 0.70M propanoic acid (HC₂H,CO₂) solution. Propanoic acid is a weak acid with K=1.3 × 10. What mass of NaC₂H,CO₂ should the student dissolve in the HC₂H5CO₂ solution to turn it into a buffer with pH = 4.52? You may assume that the volume of the solution doesn't change when the NaC₂H,CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. 0 Explanation 83°F Mostly sunny A Check F4 $ X C % Ś F6 4 Q Search F7 & FB alc H F9 F10 © 2023 McGraw Hill LLC.

In this lab, we will experimentally determine the titration curve for the titration of a weak acid solution against a strong base solution. The weak acid we will use is potassium hydrogen phthalate, KHP, its chemical structure is shown below. KHP is an ionic compound composed of a potassium cation K+ and a hydrogen phthalate anion HP–. HP– is a weak acid and upon dissolving in water, can lower the pH of the solution. (a)  Suggest the chemical reaction(s) when a solid sample of KHP is dissolved in water, writing out the chemical equations for them. (b)  Sketch the structure of KHP from above and circle the hydrogen atom that is responsible for its acidity. (c)  Calculate the pH of a solution made of 0.50 g of KHP and 50 mL of water. KHP has a molar mass of 204.2 g and at 25 °C has a pKa of 5.4.
