1.)A 75 mL solution of .400 M chlorous acid is titrated with a .125 M solution of sodium hydroxide. What is the pH of the solution after 20 mL of the sodium hydroxide solution has been added? Ka for chlorous acid is 1.1 x 10-2. (hint: your answer should contain three significant figures) 2.)The compound MX has a Ksp = 4.58 × 10−6. Calculate the concentration of M+ ions in a solution made by adding 4.18 g of MX to 483 mL of 0.273 M KX. Report your answer to THREE significant figures. You may (but are not required to) enter your answer in scientific notation; for example, if your answer is 2.44 × 10−2, you would enter 2.44E-2. The E must be uppercase. 3.)A 75 mL solution of .400 M chlorous acid is titrated with a .125 M solution of sodium hydroxide.
