Respuesta :
H3po4) is colorless, syrup + Potassium Hydroxide(3koh) -> Tripotassium phosphate(k3po4) + Water (3h2o which means it has 3 water molecules). Thus it is a double replacement reaction. So the correct option is B.
What is double replacement reaction?
Double replacement reactions occur when parts of two ionic compounds are exchanged, making two new compounds. These reaction also known as double displacement, exchange, or metathesis reactions.
A-B + C-D → A-C + B-D
In general, three chemical processes may lead to the removal of ions from solution, therefore serving as a driving force for double-replacement reaction to occur:
The formation of an insoluble product (known as a precipitate).
The formation of either a weak electrolyte or a nonelectrolyte.
The formation of a gas which escapes from solution.
