The statement 'Heating the decalcification solution increases the rate of decalcification' is true.

• A. True
• B. False
• C. It depends on the solution
• D. Only if acid present

Answer: (B)

Temperature can affect how quickly decalcification happens, but heating does not universally speed up decalcification for every decalcifying agent. The overall rate depends on the specific solution and how it interacts with the tissue. With strong acid decalcifiers, warming can accelerate calcium salt dissolution, yet it also increases the risk of over-decalcification and damage to tissue morphology and staining quality, so the practical benefit is not guaranteed. For chelating agents like EDTA, decalcification is slower and temperature effects can vary; higher temperatures can alter chelation kinetics and potentially compromise tissue integrity or antigen preservation. Because the speed gain from heating is not consistent across all solutions and tissues, the statement is not universally true.
