A sample of 2500ml of 0100m hno2 in a flask is titrated, Ask an Expert

Academics

A sample of 25.00mL of 0.100M HNO2 (in a flask) is titrated with 0.150M of NaOH solution (in a buret) at 25C. (Constants in Chemistry the Central Science Textbook).

a) Calculate the volume of the NaOH solution needed to completely neutralize the acid in the flask.

b) Calculate the pH for a, the initial acid solution in the flask

c) the point at which 8.00mL of base has been added

d) The equivalence point

e) The point at which 20.00mL of the base has been added. Box the pH values calculated (Hint: An approximation may not be applicable to all calculations)
