Consider the solubility products (Ksp values) for the following compounds:SrSO4 (Ksp = 7.6 x 10−7), BaSO4 (Ksp = 1.5 x 10−9), SrCO3 (Ksp = 7.0 x 10−10), BaCO3 (Ksp = 1.6 x 10−9)Which anion is the harder base, CO32− or SO42−? Justify your answer.

Q1: a) Arrange the compounds in order of decreasing pKa, highest first. ОН ΟΗ ῸΗ дон ОН ОН CI Br

(4 pts - 2 pts each part) A route that can be taken to prepare a hydrophobic (water-repellent) aerogel is to start with trichloromethylsilane, CH3SiCl3 as the silicon source. a. What is the chemical reaction that this undergoes to form a product with Si-OH groups? Write as complete of a chemical equation as you can. CI CI-SI-CH3 CI b. The formation of a byproduct is what drives this reaction - what is the byproduct (if you didn't already answer it in part (a)) and how/why does it form?
