3.5 Solubility Rules

Front

What are the alkali metals?

Back

Alkali metals are the elements found in Group 1 of the periodic table, which include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). They are known for being highly reactive, especially with water.

Front

What is the solubility rule for nitrates?

Back

All nitrates (NO3-) are soluble in water.

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two solutions react and is often seen in chemical reactions.

Front

What is the solubility rule for chlorides?

Back

Most chlorides (Cl-) are soluble in water, except for those of silver (Ag+), lead (Pb2+), and mercury (Hg2+).

Front

What is the solubility rule for sulfates?

Back

Most sulfates (SO4^2-) are soluble in water, except for those of barium (Ba2+), lead (Pb2+), and calcium (Ca2+).

Front

What is the solubility rule for carbonates?

Back

Most carbonates (CO3^2-) are insoluble in water, except for those of alkali metals and ammonium (NH4+).

Front

What is the solubility rule for hydroxides?

Back

Most hydroxides (OH-) are insoluble in water, except for those of alkali metals and barium (Ba2+).

Front

What is the solubility rule for phosphates?

Back

Most phosphates (PO4^3-) are insoluble in water, except for those of alkali metals and ammonium (NH4+).

Front

What is the solubility of Na2S?

Back

Na2S (sodium sulfide) is soluble in water.

Front

What is the solubility of CaS?

Back

CaS (calcium sulfide) is soluble in water.
