Select the appropriate answer for the given question:
Answer variants:
The compound's chemical name is sodium hydrogen carbonate \(NaHCO_3\). One of the raw materials used in its production is sodium chloride.
\(NaCl + H_2O + CO_2 + NH_3 \rightarrow NH_4Cl + NaHCO_3\)
\(NaCl + H_2O + CO_2 + NH_3 \rightarrow NH_4Cl + NaHCO_3\)
Solution 'B' with pH \(6\) has more \(H^+\) ion concentration and is acidic in nature.
Solution 'A' is basic as its pH is \(8\).
Solution 'A' is basic as its pH is \(8\).
The water of crystallisation is the fixed number of water molecules present in one formula unit of salt.
For example, hydrated copper sulphate \(CuSO_4. 5H_2O\) contains five water molecules in one formula unit of copper sulphate.
\(CuSO_4. 5H_2O \rightleftharpoons CuSO_4 + 5H_2O\)
For example, hydrated copper sulphate \(CuSO_4. 5H_2O\) contains five water molecules in one formula unit of copper sulphate.
\(CuSO_4. 5H_2O \rightleftharpoons CuSO_4 + 5H_2O\)
1. What is meant by the term water of crystallisation? How would you show that copper sulphate crystals contains water of crystallisation?
