Question

In a titration experiment to estimate the amount of FeSO4 in a given solution,
a primary standard solution of oxalic acid containing 0. 3 g of oxalic acid in
250 mL was prepared.
20 mL of the prepared oxalic acid solution was titrated against potassium
permanganate solution(secondary standard) and the titre value at the end point
was 13.2 mL.
The given FeSO4 sample solution was diluted and made up to 100 mL in an
SMF.
20 mL of the made up FeSO4 solution was titrated against the standardised
potassium permanganate solution and the titre value at the end point was 15.5
mL.
Calculate the amount of FeSO4 in the given solution, Given equivalent weight of
oxalic acid is 63 g and that of FeSO4 is 278 g. Your calculated values should be
written, corrected to the fourth decimal value.

Answer 1

Answer:

A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: x is really 1x. Sometimes a letter stands in for the number.
