The dissolution rate of a substance is affected by the surface area that can react with the liquid it is dissolving in. Powdering it increases the surface area so it increases the dissolving rate.

All of the above can help a substance dissolve faster in a solvent. Crushing the substance to a powder increases the surface area for interaction, agitation helps distribute the solute throughout the solvent, and raising the temperature can increase the kinetic energy of particles, speeding up the dissolution process.


Why must a substance be in the powder form before dissolving it?

The actual surface area of the substance is larger when it's in powdered form, and as dissolving only happens at the surface area, dissolving a powder is a faster process. It is not an absolute necessity , though. When the substance is not powdered, it will dissolve as well, as the amount you can dissolve is only dependent on the substance involved. However, in powdered form, it will dissolve quicker.

Why does baking powder half dissolve in water?

Baking powder is Sodium Bicarbonate a polar compound that is particularly amenable to water (a polar solvent). So Baking powder will dissolve faster than a non-polar powder like Talcum powder. Also baking power is very finely ground and will present a large surface area to the water which hastens dissolving. Salt in comparison although a strongly polar compound is course ground and will take longer to dissolve.
