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?

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

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.

(use SF, units; show all work; answers in box) 1. a: Acetic acid (HC2H302) is a weak electrolyte. What substances are present in HC2H3O2 (ag)? b: Chloric acid (HCIO3) is a strong electrolyte. What substances are present in HCIO3 (aq)? 2. Identify each of the following substances as a strong electrolyte, weak electrolyte, or nonelectrolyte: a. CSH1206 (glucose) b: HF с. НI d. H2O2 e. LINO3 3. Give the Arrhenius and Bronsted definitions of acids and bases. Why are the Bronsted definitions more useful?

3. 8.0 mL of HCI was added into a 10.0 mL graduated cylinder and weighed on a centigram balance. Looking at the photo to the right, record the mass to the nearest 0.01 Sost ha 12.71 gram in your data table (line 4)

My teacher says the answer is 0.84 M, but how?
