Question

Two salts react with each other to form:

• A. Two new salts
• B. Salt and water
• C. Salt and hydrogen gas
• D. Salt and oxygen gas

Answer 1

The correct option is A Two new salts

Two salts present in a solution react with each to form two more new salts through a double displacement reaction.
Salt 1 + Salt 2 $\to$ Salt 3 + Salt 4
AB + CD $\to$ AD + CB
For example: $NaCl+AgN{O}_3\to AgCl+NaN{O}_3$
