Question

state the physical conditions of reactants in which the reaction between sodium sulphate and barium chloride will not take place

Answer 1

Answer:

Explanation:

Answer:For a: It is a type of double displacement reaction.For b: The solution of copper sulfate looses its blue color.Explanation:For a:When barium chloride reacts with sodium sulfate, it leads to the production of barium sulfate and sodium chloride. This reaction is a type of double displacement reaction because here, exchange of ions are taking place.The chemical equation for the above reaction follows:Both the reactants must be present in aqueous state to react.For b:When iron nails are put in the copper sulfate solution having blue color, the color of the solution fades away. This happens due to the replacement of copper ions with iron ions because iron is more reactive metal than copper.The chemical equation of the above reaction is:This reaction is a type of single replacement reaction. In this reaction more reactive metal replaces a less reactive metal from Its chemical reaction.
