What is an insoluble solid that forms as the result of a double-displacement reaction called?

Answer 1

It is called a precipitate because it "falls out" of solution, like precipitation such as rain falls out of the sky.

When two aqueous ionic solutions react, a double displacement (double replacement) reaction occurs, where one of the products must be a precipitate, an insoluble gas, or water.

The general form for a double displacement reaction in which a precipitate forms, also called a precipitation reaction or salt metasthesis, is as follows: #"AX"+"BY"##rarr##"AY"+"BX"#, where #"A and B"# are cations and #"X and Y"# are anions.

An illustration of salt metastasis or precipitation reactions.

#"AgNO"_3("aq")" + NaCl(aq)"##rarr##"NaNO"_3("aq")" + AgCl(s)"#

#"AgNO"_3("aq")" + NaCl(aq)"##rarr##"NaNO"_3("aq")" + AgCl""darr#

You can use the symbol #("s")# or #darr# to represent the precipitate.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
