Prepare 100.00ml of 0.10M HCl (stock solution of 3.00M available)
Prepare 100.0 ml solution out of 0.10M acetic acid (CH3COOH) (stock solution of 2.00M available)
When 100.0 mL of 2.00 M Ce(NO3)3 is added to 100.00mL of 3.00M KIO3, a precipitate of Ce(IO3)3 (s) forms. Calculate the equilibrium concentrations of Ce3+ and IO- in this solution. Ksp Ce(IO3)3=3.2x10^-10
Titration example: A 100.00mL sample of 0.200M NH3 solution is titrated with a standard 2.00M HCl solution, all at 25oC. Predict the equivalence point volume and predict the pH at several points during the titration: 1) 0mL HCl added, 2) 5.00mL HCl added, 3) 10.00mL added, and 4) 15.00mL added.
How would you prepare 10 mL of a 0.25 M HCl solution if 1 M HCl was available?How much 1 M HCl is needed? How much distilled water is used?
Given this information: Solution #8 is 50mL 0.10M NH3 + 50mL 0.10M NH4NO3 Solution #10= 10mL Solution 8 + 5mL H2O + 1mL 0.10M HCl I’m being asked use the ICF calculations (with moles, not molarity) and use the Henderson-Hasselbach equation to find the pH for solution #10 I’m so lost and this is due in less than three hours. Please help
A 100.0 mL portion of a stock solution was diluted to 600.0 mL. If the resulting solution was 3.00M, what was tge molarity of tve original stock solution?
Calculate the volume of 0.10M NaOH required to neutralize (a) 10mL of 0.10M HCl (b) 10mL of 0.10M acetic acid (CH3COOH) and (c) 10mL of 0.10M H3PO4, a triprotic acid.

with steps please!
11. You have a mixture of 0.10M HCl and 0.10M HI. What is the pH of the resulting solution? a. 1.00 b. 2.00 C. 0.70 d. 0.20 e. Cannot determine with the information provided 12. The autoionization of water is an endothermic reaction. This means at higher temperatures: a. pH of pure water > 7.00 V b. pH of pure water < 7.00 C. [H3O+] > 107 V
You need to prepare a solution of .25 M HCl for the experiment you are doing today. You only have the commercially available concentrated HCl (28 % w/w) on hand. The experiment requires using HCl at three points, each using a volume of 15 milliliters. Describe how you would prepare the required amount of HCl (in exact quantities of stock HCl and water) prior to doing the experiment. Assume the density of water and the HCL solution (which is mostly...
