Explain erlenmeyer flask and 2 drops of phenolphthalein

Reference no: EM13253888

A 25.00 ml aliquot of a nitric acid solution of unknown concentration is pipette into a 125ml Erlenmeyer flask and 2 drops of phenolphthalein are added.

The above sodium hydroxide solution (the titrant) is used to titrate the nitric acid solution (the analyte).
If 16.77 ml of the titrant is dispensed from a bured in causing a color change of the phenolphthalein, what is the molar concentration of

the nitric acid (a monoprotic acid) solution?
Express the molar concentration of HNO3 to the correct number of significant figures
