Question
What is the general form for a double-replacement reaction?
A + BX ---- AX + B
AX + BY ------ AY + BX
A + B ------ AB
Solution
The general form for a double-replacement reaction is AB + CD --> AD + CB. In this type of reaction, the cations and anions switch partners. A and C are typically cations, while B and D are typically anions.
Here's how it works:
-
Start with two compound reactants, AB and CD. A and C are the cations (positively charged ions) and B and D are the anions (negatively charged ions).
-
In the reaction, the cations and anions switch partners. A (the cation from the first compound) pairs with D (the anion from the second compound) to form the new compound AD.
-
Similarly, C (the cation from the second compound) pairs with B (the anion from the first compound) to form the new compound CB.
-
The final products of the reaction are the new compounds, AD and CB.
So, the general form of a double-replacement reaction is AB + CD --> AD + CB.
