Which process(es) affect the speed of dissolution?
a.particle size and stirring only*
b.stirring only
c.particle size, temperature and stirring
d.particle size only
I raise honeybees as a sideline. I mix sugar and water as a stimulative feed, fine sugar, steering (I use a paint paddle on an electric motor), and for heavy syrup, I have to heat it in the winter, cold water wont do it. answer c is on the mark.
thanks bob
The correct answer is c. particle size, temperature, and stirring.
To determine the factors that affect the speed of dissolution, we need to consider the following processes:
1. Particle Size: When the solute particles are smaller, they have a larger surface area exposed to the solvent, which increases the rate of dissolution. Therefore, reducing the particle size of the solute enhances the speed of dissolution.
2. Temperature: Generally, an increase in temperature accelerates the dissolution process. This is because higher temperatures provide more energy, which helps break the bonds between solute particles and facilitates their movement into the solvent.
3. Stirring: Stirring or agitation aids in the dissolution process by maintaining a concentration gradient at the surface of the solute particles, ensuring continuous contact between the solute and the solvent. This allows for a faster transfer of solute particles into the solvent.
Therefore, it is clear that all three factors - particle size, temperature, and stirring - affect the speed of dissolution. Thus, the correct answer is c. particle size, temperature, and stirring.
