Short Q/A Stoichiometry

Study the effect of heat on hydrated copper sulfate. Why does this salt look colored, and why does it lose color upon heating?

Hydrated copper sulfate (CuSO₄·5H₂O) is blue in color due to the presence of water molecules in its crystalline structure. The water molecules form a complex with copper ions, which gives the crystal its characteristic blue hue. When heated, the water evaporates, and the salt loses its blue color. This is because the removal of water … Read more

Explain how the rates of forward and backward reactions change when the system approaches equilibrium.

As a system approaches equilibrium, the rates of the forward and backward reactions change. Initially, the rate of the forward reaction is higher because reactants are being converted into products. Over time, as the concentration of the products increases and the concentration of the reactants decreases, the rate of the forward reaction slows down. Simultaneously, … Read more
