Does the size of the salt being affect how fast it dissolves in water?
Size of the particles — When a solute dissolves, the action takes place only at the surface of each particle. When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution.
Does the size of particles of salt affect the solubility of a solution?
The solubility of a substance in a particular solvent is measured by the concentration of the saturated solution. Solubility does not depend on particle size; given enough time, even large particles will eventually dissolve.
What is the relationship between particle size and time it takes for the table to dissolve?
Answer: The relationship between particle size and speed it takes for the tablet to dissolve is that the smaller is the particle size of the tablet, the faster it will dissolve; or the bigger is the particle size of the tablet, the slower it will dissolve.
What affects the speed of dissolving?
The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring.
Why does salt dissolve faster in hot water?
Salt would dissolve quicker in hot water because the molecules in hot water move faster than cold water because of the higher energy, therefore the molecules of hot water move fast, they can more easily break apart the other molecules of a different substance when they come into contact.
Why do smaller grains of salt dissolve faster?
Let’s assume the solvent of interest is water. For this reason a bigger contact surface will cause a faster dissolution. Smaller crystals have more surface for the same volume (or weight) of salt. Therefore smaller grains of salt will dissolve faster than bigger ones.
How does surface area to volume ratio affect dissolved salt?
With greater surface area to volume ratio, there can be more contact between particles of solute (salt) and solvent (water) and hence it will dissolve faster. Lower surface area to volume ratio means lower rate of diffusion between particle. This is adapted by the cells in our body as well.
How to calculate the time it takes for salt to dissolve in a liquid?
Remember that to find the average time it took for the salt and sugar to dissolve in each liquid, you add the three times recorded for each one, then divide them by three. The number you get when you divide the times is the average time. Use this chart to record the time it takes for the sugar and salt to dissolve.
