Select all statements below that are TRUE. Group of answer choices To find the molarity of any acid titrated with NaOH you can use M1V1 = M2V2. When a strong acid and base are mixed in stoichiometric amounts, the solution will be neutral. Always titrate into your largest beaker. The molar ratio between an acid and a base in a neutralization reaction is always 1:1. The endpoint is when the indicator changes color.

The next questions are related to the titration of 25 mL of a 0.0950 M acetic acid solution with 0.900 M KOH. What is the initial pH of the analyte solution?

Questions 15-20 refer to the same weak base/strong acid (WB/SA) titration. The K of pyridine is 1.7 x 10-⁹. A 40.00 mL solution of 0.700 M pyridine (C5H5N) is being titrated with 1.05 M hydrochloric acid (HCI). What is the solution when 15.00 mL of titrant have been added? (Two decimal places) Type your answer...

Part A Review Constants I Periodic Table A 250.0 mL buffer solution initially contains 3.0x10-2 M of HCHO2 and 3.0×10-2 M of NaCHO2. In order to adjust the buffer pH to 4.10, should you add NaOH or HCl to the buffer mixture? NaOH HCI Submit Previous Answers Part B Correct What mass of the correct reagent should you add?

A student performed titration to determine the concentration of potassium permanganate solution with oxalic acid. The net ionic equation is as follows: 2MnO4– + 16H+ + 5C2O42- → 2Mn2+ + 10CO2 + 8H2O The titration consumed  42.31 mL of 0.1001 M oxalate solution to reach the endpoint. Determine the concentration of permanganate (M)  if 25 mL was used.

When a 19.5 mL sample of a 0.433 M aqueous acetic acid solution is titrated with a 0.434 M aqueous barium hydroxide solution, what is the pH at the midpoint in the titration? pH = %3D Submit Answer Retry Entire Group 9 more group attempts remaining

Incorrect Your answer is incorrect A chemistry student weighs out 0.414 g of citric acid (H,C,H,O.), a triprotic acid, into a 250. mL. volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.0500 M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits. 12.9 ml.
