### Water Sample Analysis in a Closed SystemConsider a water sample in a closed system with $ C_{T,CO3} = 8 \times 10^{-4} \, M $ and pH = 8.#### a) Determining Alkalinity- **Question:** What is the alkalinity of this water sample?#### b) Calculating Acid Requirement- **Question:** How much acid is required to reduce the pH of the sample to 6, assuming no exchange of $ CO_2(g) $ with the atmosphere (i.e., the system stays closed)?

Given, Ст, соз =8×10-4 , pH=8 (a) Alkalinity of the sample = pOH=14-pH⇒14-8= 6

10.00mL of 0.10M acetic acid were collected in an Erlenmeyer flask, and then diluted to 100mL with distilled water. After that, two drops of indicator were added. Then, the buret was filled with 0.100M NaOH. The titration was started by slowly adding NaOH to acetic acid. (Note: Ignore the volume of the indicator added, as the volume is tiny compared to 100mL.)

Sn2 and N (starting concentration 10 mol/L) should be separated by fractionated precipitation using H₂S. Does a pH range exist allowing to completely precipitate one metal (i.e. the remaining concentration of the precipitated ion has to be 10 mol/L or less) whereas the other stays in solution at its initial concentration? Please calculate this pH range whereby pH values below zero are set to zero! Please illustrate the situation graphically by plotting pH versus in solution/precipitating/fully precipitated for the two ions (9) Solubility product (SnS): 10; (NIS): 1021; Acid constant (H2S): 10-20, r/Concentration of H2S in water: 0.1 mol/L
You look at the solubility of Ca(OH)2 in water (Ksp = 4 x 10–10). You wait until the system reaches equilibrium and then add Cr(C2H3O2)3. (Ksp = 6.7 x 10–31 for Cr(OH)3). Would affect do you think would occur to the solubility? (increase, decrease, stay the same) Show this through a calculation (Note: Two equilibria must be considered).
