"WebThe oxidation of aldehydes to carboxylic acids is a two-step procedure. In the first step, one mol of water is added in the presence of an acidic catalyst to generate a hydrate (geminal 1,1-diol). Subsequently, the hydrate is oxidized to the carboxylic acid formally eliminating water. " - How to turn aldehyde into carboxylic acid
