The acid-base titration involving strong acids and strong bases are the easiest ones because the equivalence point will always be observed at pH 7at 25∘C. As such, only one indicator is used for this type of titration which is phenolphthalein. ...
How to answer the question: why the pink colour (from 2-3 phenolphthalein indicator) obtained at the end point of the titration in this experiment gradually disappears over time? :confused: Is it because of that the water will reverse back to the form of H+ and OH-?
You are given 4 M KoH, oxalic acid, and phenolphthalein indicator. a. How much water do you need to make 500 ml of 0.125 M KOH? b. Write a balanced chemical equation for this reaction. c. Given that Consider the titration of 60.00 mL of 0.183 M HNO3 with 0.254 M KOH. Ca...
Acidic strength refers to the tendency of a compound to give proton in the aqueous solution. Higher the tendency of a compound to give protons in the solution, higher will be the acidic strength. Answer and Explanation:1 HI is more acidic than HCl because HI can easily dona...
