Question

what are bases give two examples of a two commonly used bases​

Answer 1

BASES :-

The ionic compounds that produce negative hydroxide (OH−) ions when dissolved in water are called bases. A compound containing negative nonmetal ion as well as a positive metal ion that is held together by the ionic bond is called an ionic compound.

But what are ions?

Ions are atoms which become charged particles as a result of losing or gaining electrons. NaOH (sodium hydroxide) is an example of a base. When it dissolves in water, it generates negative hydroxide (OH−) ions and positive sodium (Na+) ions. It can be represented by the following equation:

NaOH →H2O + OH− + Na+

EXAMPLES OF BASES ......

• Sodium hydroxide, NaOH (cleaning agent, paper, pH regulator)

• Sodium carbonate, NaCO3 (paper, glass, detergent, toothpaste)

• Sodium bicarbonate, NAHCO3 (baking soda, fire extinguisher, toothpaste)

• Calcium hydroxide, or slaked lime, Ca(OH)2 (flocculant, paper)
