someone solve this for me, I'm stuck on it while practicing:
Dilute sulfuric acid and aqueous potassium hydroxide can be used to make potassium sulfate crystals using a method that includes titration. A student titrated 25.0 cm3 of 0.0500 mol / dm3 aqueous potassium hydroxide with dilute sulfuric acid in the presence of an indicator. The volume of dilute sulfuric acid needed to neutralize the aqueous potassium hydroxide was 20.0 cm3.
Describe how to prepare a pure, dry sample of potassium sulfate crystals from new solutions of dilute sulfuric acid and aqueous potassium hydroxide of the same concentrations as used in the titration
give 5 points
Name an indicator that can be used for the above titration. Also include the color change of the indicator at the end point of the titration.
