Current Question (ID: 9165)

Question:

$\text{The incorrect statement among the following is-}$

Options:

1. $\text{Sodium metal is used in organic qualitative analysis.}$
2. $\text{Sodium carbonate is soluble in water and it is used in inorganic qualitative analysis.}$
3. $\text{Potassium carbonate can be prepared by the solvay process.}$
4. $\text{Aq. solution of potassium bicarbonate is a weak base.}$

Solution:

$\text{Hint: } \text{K}_2\text{CO}_3 \text{ can't be prepared by Solvay's process.}$ $\text{Explanation:}$ $\text{The Solvay process is an industrial process that uses limestone (}\text{CaCO}_3\text{) to produce carbon dioxide (}\text{CO}_2\text{) which reacts with ammonia (}\text{NH}_3\text{) dissolved in brine (concentrated }\text{NaCl}\text{(aq)) to produce sodium carbonate.}$ $\text{Potassium carbonate cannot be prepared by Solvay process.}$ $\text{Potassium bicarbonate is fairly soluble in water which forms a alkaline solution and does not precipitate out.}$
