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?

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.
II. Titrating HCI Solution with NaOH Solution 1. Prepare a titration curve. Plot pH (on the y-axis) versus volume of NaOH solution added (on the x-axis). If your initial buret reading was not 0.00 mL, remember to subtract your actual initial reading from each of your subsequent buret readings before plotting the titration data.
