This post contains some helpful handy notes for the GPAT aspirants. H 2 SO 4 (use a dropper, H 2 SO 4 is highly corrosive) and swirl the flask gently until the salicylic acid dissolves. Gravimetric analysis relies on the contrast of the masses of two analyte-containing compounds. Carbohydrates can be viewed as hydrates of carbon, hence they are known as carbohydrates. These are extremely weak and cannot be analysed using normal titrimetric methods. Another important step is in measuring the right volume of the standard solution since molarity is a standard metric to calculate the number of moles present in a solution.
