Answer the following questions after writing the involved reaction:a. What will be the strength of potassium permanganate in gram per liter?b. Bench acid is used in this titration along with oxalic acid. Can you use HCl instead?c. A teacher asked the topper from the group, Bismita, to titrate bench acid with 0.1 N \(Na_{2}CO_{3}\). She was suggested to perform a rough titration at first. What is the significance of doing that?d. On rough estimation, bench acid was found to have a strength of around 2.4 N. If Bismita was to prepare a diluted acid solution in a 100 ml flask, what would be the extent of dilution of the acid?e. Using the same extent of dilution, if Bismita got a concurrent reading at 12.8 ml when titrating with 10 ml of \(Na_{2}CO_{3}\), what was the actual concentration of bench acid?
