1 Answer
The weak acid is the gray and yellow spheres.
Explanation:
First off, a compound that forms ions has to have positive and negative ions, and only the gray ions are positive. So, the only possible compounds are gray-green, gray-purple and gray-yellow.
A weak acid is one where not all the molecules are dissociated in solution. Here we see some gray-yellow molecules are not dissociated so gray-yellow is a weak acid not a strong one. The other combinations of positive and negative ions, gray-green and gray-purple, have no molecules in solution and so are strong acids.
