The reaction would produce two kinds of ketones as products
Reaction of alkyne with mercuric sulfate, water and sulfuric acid
Mercuric sulfate acts as a catalyst, making it easier to add water across the alkyne's triple bond. The ketone product is produced by tautomerization of the enol intermediate, which is the result of the reaction.
The hydrogen in this hydration reaction binds to the carbon in the alkyne with more hydrogen substituents, following a Markovnikov addition pattern.
