How can an aldehyde be distinguished from a ketone?

An aldehyde will react with Tollen's reagent to form a characteristic silver mirror, whereas a ketone will not react.  This is because an aldehyde can be oxidised to a carboxylic acid, reducing Tollen's reagent, whereas a ketone cannot be oxidised so cannot take part in the reaction.
