In the Bottle-Forbes method, what is done immediately after adding water in portions?

• A. The mixture is shaken thoroughly
• B. The mixture is heated
• C. The mixture is cooled
• D. The mixture is filtered

Answer: (A)

After each portion of water is added, the mixture is shaken thoroughly. The Bottle-Forbes method relies on controlled, incremental hydration, and thorough shaking ensures that the added water contacts all solid particles, breaks up any clumps, and promotes uniform dissolution before the next portion is added. Heating or cooling would alter solubility and kinetics, and filtering would be a later step, not the immediate action after adding water.
