Prepare aqueous solutions of various solid salts available in the labo

1.	Prepare aqueous solutions of various solid salts available in the laboratory,Observe what happens when aqueous solution of sodium hydroxide is added tothese. Prepare a chart of double displacement reactions based on these observation.Project
Answer» Answer: A double - displacement reaction occurs when PARTS of two ionic compounds are exchanged, making two new compounds. A characteristic of a double - displacement equation is that there are two compounds as reactants and two different compounds as products. EXAMPLES : We have an acidic solution of HCl. Lets write the equation of reaction with HCl as follows : HCl (aq) + NaOH (aq) —> NaCl (aq) + H₂O (L) This is a double displacement reaction. Another example COULD be a solid of Calcium Carbonate with sodium hydroxide. The reaction is as follows : CaCO₃(s) + 2NAOH (aq) —> Na₂CO₃ (aq) + CA(OH)₂ (aq) This is an example of a double displacement reaction.

Answer:

A double - displacement reaction occurs when PARTS of two ionic compounds are exchanged, making two new compounds.

A characteristic of a double - displacement equation is that there are two compounds as reactants and two different compounds as products.

EXAMPLES :

We have an acidic solution of HCl.

Lets write the equation of reaction with HCl as follows :

HCl (aq) + NaOH (aq) —> NaCl (aq) + H₂O (L)

This is a double displacement reaction.

Another example COULD be a solid of Calcium Carbonate with sodium hydroxide.

The reaction is as follows :

CaCO₃(s) + 2NAOH (aq) —> Na₂CO₃ (aq) + CA(OH)₂ (aq)

This is an example of a double displacement reaction.
