Determining the Acetic Acid in Vinegar by Titration For this experiment it is best to choose a "white vinegar" that is, a colourless vinegar rather than a "brown vinegar". The colour of a "brown vinegar" can mask the colour change at the end point of the titration.

When a weak acid such as acetic acid is titrated with a strong base such as aqueous sodium hydroxide solution, the pH at the equivalence point will be greater than 7. Suitable indicators for this experiment are phenolphthalein or thymol blue. Procedure to titrate the acetic acid in vinegar: Rinse a clean mL conical erlenmeyer flask with water.

Rinse a clean Add 2 drops of phenolphthalein indicator to the vinegar. The solution will remain colourless Rinse a clean Fill the burette buret with this standardised 1. Set up the equipment as in the diagram on the right.

Run NaOH aq from the burette buret into the conical erlenmeyer flask until the solution changes colour from colourless to pink.

Determination of the molar volume of

Repeat the titration carefully several times until concordant titres are achieved.The molar volume, symbol V m, is the volume occupied by one mole of a substance (chemical element or chemical compound) at a given temperature and pressure.

It is equal to the molar mass (M) divided by the mass density (ρ). Properties include measurement of density and determination of partial molar volume, determination of surface tension, and measurement of viscosity by capillary flow method. The methods will be discussed separately to understand simultaneously such properties of the liquid mixture: cyclohexane and benzene.

Leon M. . It must be emphasized, the partial molar volume of a substance in a solution is not equal to the Molar Volume of the substance when pure;. This determination can then be used in Equations 7 and 8 to obtain our desired results, and. The Volume of Mixing. CHEMISTRY HIGHER SECONDARY - SECOND YEAR VOLUME - I Untouchability is a sin Untouchability is a crime Untouchability is inhuman TAMILNADU TEXTBOOK CORPORATION.

This page describes, with fully worked out examples, how to calculate the volume of gas formed from a given masses of reactants. You need to know the formula connecting moles, mass and formula mass AND know how to use the molar volume in these calculation methods.
