What is the term for a solid that forms when two solutions are mixed?
Inessa [10]

Option D

A precipitate is the term for a solid that forms when two solutions are mixed

<u>Explanation:</u>

A solid set from a couple of solutions is termed a precipitate. A precipitate is an unsolved solid that makes when a pair of solutions are fused and react chemically. Unsolvable means that the solid will not melt.  When the effect transpires in a liquid solution, the solid developed is denominated the 'precipitate'.

The substance that generates the solid to make is termed the 'precipitant'. Seldom the development of a precipitate symbolizes the existence of a chemical reaction. Precipitation may additionally transpire immediately from a supersaturated solution.
