Ka= 1.76 x 10-5 for HC2H3O2 What is the pH of this solution? Table 1 Solution Buffer solution (you did this earlier) A acetic acid, 0.1 M (mL) sodium acetate, 0.1 M (mL) distilled water (mL) After 1 mL of 0.1M NaOH is added to this solution, what is the pH?

please answer questions 1,2, and 3 and show the steps. thanks!!

can you help me and line it exactly like this because i keep doing it and its says its wrong

Commercial perchloric acid is an aqueous solution containing 70% by mass HCIO, (100.46 g mol") and has a density of 1.664 g mL. How many mL of commercial perchloric acid should be used to prepare a 340 mL 0.365 M HCIO,(ag) solution? Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma () as decimal separator.

How can we find the volume for both questions?

Please help me answer questions 1 and 2. (Questions attached below) 1. When you arrive at the lab, 2.0 M H2SO4(aq) and 2.0 M HC2H3O2(aq) will be present. Youwill need to dilute these solutions using beakers and graduated cylinders from your drawerand DI water.i. Calculate the volume of the 2.0 M HC2H3O2(aq) and DI water needed to create 50.0 mLof 1.05 M HC2H3O2(aq).ii. Calculate the volume of the 2.0 M H2SO4(aq) and DI water needed to create 50.0 mL of0.75 M H2SO4(aq). 2. A 48.33-mL sample of 0.150 M NaBr is titrated into 50.00 mL of 0.145 M AgNO3. Bothsolutions had the same initial and final temperatures. The reaction occurred in a calorimeterwith a known heat capacity and produced 1546.03 J of heat.i. Write a balanced equation that is occurring.ii. Determine the theoretical yield of the solid.iii. Calculate the enthalpy of the reaction (kJ/mole of precipitate).

Use the formula pH=-log[H^+]. The variable pH represents the level of acidity or alkalinity of a liquid on the pH scale, and [H^+] is the concentration of hydrogen ions in the solution. Determine the value of [H^+] (in mol/L) for the following liquids, given their pH values. Express your answers in scientific notation with three significant digits.  a.) Tea pH=5.5  b.) Milk pH=6.2   What is the concentration of hydrogen ions in tea? What is the concentration of hydrogen ions in milk?

If 50.1 mL of 0.128 M hydrochloric acid requires 17.5 mL of NaOH solution to reach the endpoint, what is the molarity of the NaOH solution? Include three decimal places in your answer.
