Which factor can increase the rate at which a solute dissolves in a, Stirring the solution, Decreasing the contact between the solute and solvent, A student adds sugar into water and notices that some sugar remains at the bottom even after stirring. What is the most likely reason?, The water is too hot, The solution has reached saturation, Which situation will cause a solid solute to dissolve more slowly?, Using powdered solute, Stirring the solution, A student wants to dissolve sugar as quickly as possible. Which method is the most suitable?, Use cold water without stirring, Use hot water and stir, A solution is described as unsaturated when:, No more solute can dissolve, More solute can still dissolve in the solvent, Why does a powdered solute usually dissolve faster than a large piece of the same solute?, It has a larger surface area exposed to the solvent, It has a smaller mass, Two students use the same amount of sugar and water. Student A uses hot water, while Student B uses cold water. Which student will most likely observe faster dissolving?, Student B, Student A, Which variable should be kept constant when investigating the effect of temperature on the rate of dissolving?, The amount of solute used, The temperature of the water, saturated sugar solution contains some undissolved sugar at the bottom. What happens if the mixture is left at the same temperature?, All the sugar will eventually dissolve, The undissolved sugar will remain unless conditions change, Which combination would generally result in the fastest dissolving?, Large solid pieces + cold water + no stirring, Small particles + hot water + stirring
