You are titrating 50 ml. of nitrous acid with sodium hydroxide(0.15 M). Equivalence is reached at 22.0 ml of NaOH delivered.Calculate the pH of the solution in the flask: - before thebeginning of the titration - after the delivery of 5 ml. of titrant- at half$equivalence - at equivalence -after delivery of 23 ml. oftitrant. -------------Give detail Show ALL WORK, UNITS and useICE/reaction table and ML (no millimoles). Please be clear in howyou get numbers for everything like the reaction table... I'veasked this before and have gotten incomplete answers.
