Answer:
Explanation:
When you drop an Alka-Seltzer tablet into water, it immediately starts to bubble and fizz. Why does this happen? What you're observing when you make an Alka-Seltzer drink is an example of a gas evolution reaction. In this type of chemical reaction one of the products is a gas, which can be seen as bubbles in an aqueous solution.
Gas evolution reactions are one example of double displacement reactions, where two ionic compounds mix. The negatively charged ions, or anions, essentially switch partners, forming new chemical compounds in the product.
