what is the concentration of the naoh(aq) given that 20.8cm3 of 0.0500 moldm-3 h2so4 neutralises 25.0cm3 of it?

Suppose 0.917g of sodium chloride is dissolved in 100.mL of a 54.0mM aqueous solution of silver nitrate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the sodium chloride is dissolved in it. Round your answer to 3 significant digits

determination of ph of acetic acid solution like 0.1m,0.05m hcl,and 0.0125m concentration by using quinhydrone and calomel electrode to calculate degree of dissociation constant

Were were estimating dissolved CO2 in water by American Public Health Association method. It was a Titrimetric Method using phenolpthalein indicator.

Titrant used was NaOH and analyte was sample water.

Our instructor said that on adding phenolpthalein if the water sample turns pink then it can be concluded that no free CO2 is present. But how's it so?
