  2. STAAR 2013 #40; RC1; Supporting1. A worker built a sidewalk and pressed some large salt particles into the concrete while it was still wet. When the concrete was dry, the worker washed the sidewalk with the water. The picture below shoes the sidewalk after it was washed:What most likely happened to the salt?F. It evaporated into a gasG. It turned into concreteH. It dissolved in the waterJ. It turned into a solid
