10 cm of 0.10 mol dm- aqueous iron (II) sulphate is titrated against 0.025 mol dm-3 aqueous potassium manganate (VII) in the presence of an excess of both hydrogen ion and
fluoride ions. It is found that exactly 10 cm of the manganate (VII) solution is required to
reach the end point. What is the oxidation number of the manganese at the end point.​

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
