Water

Water is a compound that is made up of two hydrogen atoms and one oxygen atom. The chemical formula for water is H2O. When water dissociates, it breaks down into its component ions, which are hydrogen ions (H+) and hydroxide ions (OH-). The chemical equation for the dissociation of water is:

2H2O ⇌ H3O+ + OH-

Aluminum sulfate

Aluminum sulfate is a compound that is made up of two aluminum atoms, three sulfate ions, and 18 water molecules. The chemical formula for aluminum sulfate is Al2(SO4)3•18H2O. When aluminum sulfate dissociates, it breaks down into its component ions, which are aluminum ions (Al3+), sulfate ions (SO42-), and hydrogen ions (H+). The chemical equation for the dissociation of aluminum sulfate is:

Al2(SO4)3•18H2O ⇌ 2Al3+ + 3SO42- + 18H2O

Sodium hydroxide

Sodium hydroxide is a compound that is made up of one sodium atom and one hydroxide ion. The chemical formula for sodium hydroxide is NaOH. When sodium hydroxide dissociates, it breaks down into its component ions, which are sodium ions (Na+) and hydroxide ions (OH-). The chemical equation for the dissociation of sodium hydroxide is:

NaOH ⇌ Na+ + OH-
