Predict the products of the following reaction:
RbNO2 +BaCO3->

The products for the reaction of Rubidium nitrite and Barium carbonate has been Barium nitrite and Rubidium carbonate.

Rubidium nitrite has been the binary ionic compound found to be acidic in nature. While barium carbonate has been the basic salt with the potency to be poisonous to humans.

The reaction between an acid and a base has been the neutralization reaction with the formation of salt and water. The reaction between rubidium nitrite and barium carbonate will be:

The reaction has been the displacement reaction with the tendency to displacement.

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

Explanation:

The balanced reaction equation is shown below;

2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2

This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.

The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.

the answer is b. dilution
