The number of moles of K2Cr2O7 that will be needed to react completely...
To determine the number of moles of K2Cr2O7 needed to react completely with one mole of ferric sulphite in acidic medium, we need to first write and balance the chemical equation for the reaction.

The balanced equation for the reaction between K2Cr2O7 and Fe2(SO3)3 in acidic medium is as follows:

K2Cr2O7 + 14H+ + 6Fe2(SO3)3 → 2K+ + 2Cr3+ + 7H2O + 6Fe3+ + 6SO4^2-

From the balanced equation, we can see that the stoichiometric ratio between K2Cr2O7 and Fe2(SO3)3 is 1:6. This means that 1 mole of K2Cr2O7 reacts with 6 moles of Fe2(SO3)3.

Since we are given that we have 1 mole of Fe2(SO3)3, we can calculate the number of moles of K2Cr2O7 needed by using the stoichiometric ratio.

Number of moles of K2Cr2O7 = 1 mole of Fe2(SO3)3 × (1 mole of K2Cr2O7 / 6 moles of Fe2(SO3)3)

Simplifying the expression, we get:

Number of moles of K2Cr2O7 = 1/6 moles

Therefore, the correct answer is option 'D', 1.0 mole.
