Write the following in the form of a word equation:
2NaOH + CaBr2 → Ca(OH)2 + 2NaBr
In the formula CaBr2 what does Ca stand for and what is its valency?
Sodium hydroxide + Calcium bromide → Calcium hydroxide + Sodium bromide; calcium; 2
The word equation will be written as:
Sodium hydroxide + Calcium bromide → Calcium hydroxide + Sodium bromide.
Ca stands for calcium. From the formula CaBr2 it is evident that the valency of calcium is 2 and the valency of bromine is 1.
