You are given four different aqueous solutions and told that they each contain NaOH, Na2CO3, NaHCO3, or a mixture of these solutes. You do some experiments and gather these data about the samples. Sample A: Phenolphthalein is colorless in the solution. Sample B: The sample was titrated with HCl until the pink color of phenolphthalein disappeared, then methyl orange was added. The solution became pink. Methyl orange changes color from pH 3.01 (red) to pH 4.4 (orange). Sample C: Equal volumes of the sample were titrated with standardized acid. Using phenolphthalein as an indicator required 15.26 mL of standardized acid to change the phenolphthalein color. The other sample required 17.90 mL for a color change using methyl orange as the indicator. Sample D: Two equal volumes of the sample were titrated with standardized HCl. Using phenolphthalein as the indicator, it took 15.00 mL of acid to reach the equivalence point; using methyl orange as the indicator required 30.00 mL HCl to achieve neutralization. Identify the solute in each of the solutions.

One of your friends who likes gardening is attempting to make a solution that will increase some trace nutrients while also making the soil less acidic.* The planned solution will have the following concentrations: 0.03 M NaOH 0.008 M CaCl2 8 x 10-12 M Fe(NO3)2 You're going to help your friend out by checking to see if anything will precipitate out of this solution. Your friend is particularly worried about Ca(OH)2 [Ksp = 6.5 x 10-6] and Fe(OH)2 [Ksp = 7.9x10-16]. Your friend thinks they have done the math correctly so that no precipitates will form, but they don't know anything about ionic strength corrections.(NOTE: Assume molality = molarity. There's probably not much of a difference.) a) Calculate the ionic strength of the solution. b) Calculate the activity of hydroxide ions, aOH- c) Calculate the activity of Ca2+ ions. d) Calculate the activity of Fe2+ ions.
