Question

10ml of commercial vineger is diluted to 100 ml with distalled water when we titrate 10 ml of this solution with 0.15 M standardized sodium hydroxide we found that we need 12 ml of basic solution to reach the end point if the atomic weight of C is 12 oxygen is 16 and hydrogen is 1 calculator the following. 1.number of Gram of acetic acid in commercial vineger. 2.percentage of acetic acid in commercial vineger. 3. write the chemical equation between acetic acid and sodium hydroxide​

Answer 1

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)
