Chapter 13.9, Problem 15P

Find the pH of a 0.120 M solution of HNO2. Find the pH ignoring activity effects (i.e., the normal way). Find the pH in a solution of 0.050 M NaCl, including activity

Please help me answer these three questions. Required info should be in data table.

Draw the major organic substitution product or products for (2R,3S)-2-bromo-3-methylpentane reacting with the given nucleophile. Clearly drawn the stereochemistry, including a wedged bond, a dashed bond and two in-plane bonds at each stereogenic center. Omit any byproducts. Bri CH3CH2O- (conc.) Draw the major organic product or products.

Tartaric acid (C4H6O6) is a diprotic weak acid. A sample of 875 mg tartaric acid are dissolved in 100 mL water and titrated with 0.994 M NaOH. How many mL of NaOH are needed to reach the first equivalence point? How many mL of NaOH are needed to reach the second equivalence point?

Including activity, calculate the solubility of Pb(IO3)2 in a matrix of 0.020 M Mg(NO3)2.

Including activity coefficients, find [Hg22+] in saturated Hg2Br2 in 0.00100 M KBr.

Including activity, calculate the pH of a 0.010 M HCl solution with an ionic strength of 0.10 M.

Can I please get the graph 1: Concentration vs. Density?
