1. In the lab, you will prepare a 1.0 L, 0.10 M ammonium chloride solution using a 1.0 M ammonium chloride stock solution. How much of the stock solution will be used to prepare the diluted, 0.10 M solution? Report your answer with 1 significant figure in mL. Do not include units in your answer and do not type your answer in scientific notation. 2. In the lab, you will prepare a 1.0 L, 0.10 M acetic acid solution using...
please show work and use the ICE box to solve
please use this picture instead, I posted the wrong
problem.
thank u!
the bottom picture is the right one
here is another picture, hopefully it is clearer

a. What's the pH after 10.0 mL of 0.10 M HCl is added to a 1.0-L buffer solution composed of 0.050 M HC3H5O3 and 0.025 M NaC3H5O3 b. Where in the titration process is a 30.0 mL of 0.10 M selenous acid, H2SeO3 with the addition of 22.5 mL of 0.20 M NaOH?
1. Using the given information answer the following questions with corresponding answers. (a) Serine is a diprotic acid (Ka1 = 6.17 × 10-3 and Ka2 = 7.08 × 10-10) that can have three different forms in solution: H2S+, HS, and S- (Note: S is not sulfur in these formulas). What would be the concentration of H2S+ in the solution of 0.105M Na+S-? Group of answer choices 8.29 × 10-8 M 1.62 × 10-12 M 9.62 × 10-9 M 4.15 ×...
Consider 1.0 L of a solution which is 0.45 M HF and 0.2 M NaF (Ka for HF = 7.2 x 10-4). Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH values to two decimal places. Calculate the pH after 0.10 mol of HCl has been added to the original solution. Assume no volume change on addition of HCl. Why do we need to convert to Kb? I know...
