Question- A 25.0ml aliquot of vinegar was diluted to 250 ml in volumetric flask. Titration of a 50ml aliquot of the diluted solution requires an average of 43.88ml of 0.09600M NaOH.
Calculate Weight Volume of acetic acid in the vinegar solution? That's the grams of acetic per 100ml of vinegar solution
I am in need please provide me complete solution for the above problem so I can get right solution
400 M formic acid (HCOOH) solution freezes at -0.758 degrees C. Calculate the Ka of the acid at that temperature. (hint: assume that molarity is equal to molality. Carry out your calculations to three sig figs and round off to two for Ka).
A solution of .162 M NaOH is used to neutralize 25.0 mL of a H2SO4 solution. if 32.8mL of the NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution? H2SO4(aq)+2NaOH(aq)>Na2SO4(aq)+2H2O(l)
Calculate the ph at the equivalence point when 50 mL of .050 M HBrO is titrated with 0.100 M NaOH. Ka= 2.5 X 10^-9 for HBrO.
