Question

● Which kind of reaction produce insoluble salt?
● What is meant by double displacement reaction?

Answer 1

neutralisation reaction produces in soluable salt
the double displacement reaction means exchange of radicals

Answer 2

first answer : In precipitation reactions, an aqueous salt solution is mixed with another aqueous salt solution to form a solid precipitate, if one of the resulting salts is insoluble. If the new salts that can form are soluble, then no reaction occurs

second answer : A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
