Determine the products of the reaction for
NaOH + CaCO3 →
Select one:
a. CaOH and NaCO3
b. Ca(OH)2 and Na(CO3)2
c. Ca2OH and Na(CO3)2
d. Ca(OH)2 and Na2CO3
Sodium hydroxide (NaOH) reacts with calcium carbonate (CaCO3) to
form calcium hydroxide (Ca(OH)2) and sodium carbonate
(Na2CO3).
Hence, option d. is the correct answer.
Note: In calcium hydroxide, calcium ions have +2 charge and each
hydroxide ion has -1 charge. Hence, the formula of calcium
hydroxide will be Ca(OH)2.
Also in sodium carbonate, each sodium ion has +1 charge and
carbonate ion has -2 charge. Hence, the formula of sodium carbonate
will be Na2CO3
