The depression in freezing point of water observed for the same amount of acetic acid, trichloroacetic acid and trifluoroacetic acid increases in the order given above. Explain briefly.

Acidity diprotic acids in aqueous solution increases in the order

Fluoroacetic acid Is stronger acid than chloro acetic acid. Explain, why ?

Fluoroacetic acid is stronger than acetic acid. Explain why ?

Sulphanilic acid is insoluble in water and organic solvents. Explain.

19.5 g of CH_2FCOOH is dissolved in 500 g of water. The depression in the freezing point of water observed is 1.0° C. Calculate the van’t Hoff factor and dissociation constant of fluoroacetic acid.
