While working in the laboratory, you find a bottle containing an unknown concentration of aqueous potassium hydroxide. To determine its concentration, you take 25.0 mL of the KOH solution and titrate it with a 0.100 M solution of H2SO4. You add a bromothymol blue indicator which changes color at pH close to 7 and observe that it turns from yellow to blue when 31.2 mL of the H2SO4 solution is added. What is the concentration of the KOH solution?

Questions 3, 4, & 5 pls
(3) You will titrate a solution of an unknown acid (HX(aq)) by adding NaOH(aq). Suppose that 25 mL of 0.5 M NaOH(aq) is needed to reach the equivalence point. How many moles of HX were present initially? Show the calculation. (4) You will titrate acid solutions by adding 0.2-0.3-mL or 2-3-mL portions of NaOH(aq). When should you add the smaller volume? (5) The concentration of an aqueous solution of NaOH cannot be accurately determined...

Question 6 (1 point) In your pre-lab, you were asked to determine the concentration for a 25.00 mL sample of acetic acid, CH3COOH (K= 1.8 x 10-5) of unknown concentration. Suppose you now repeat that same titration, using another 25.00 mL sample of that same unknown acetic acid and the same concentration of NaOH as a titrant. However, before you start titrating, you add an additional 100 mL of water to the flask containing our sample of acid. Everything else...

In the lecture we used titration of sodium carbonate with hydrochloric acid as an example to explain how to titrate a weak base with a strong acid. Suppose that you are using HNO3 to titrate Na3PO4, describe how to calculate pH at following different titration stages: (a) before titration (b) at 19 equivalence point (c) at 3rd equivalence point (d) between 2nd and 3rd equivalence points (e) after 3rd equivalence point Calculation is not required, simply write the...
