dilute.
The molarity of a solution can be changed by adding more solute to increase the concentration or by adding more solvent to decrease the concentration.
You can decrease the concentration of a solution by diluting it with a solvent, such as water. Another way is by adding more solvent to the solution to increase its total volume, which effectively lowers the concentration of the solute in the solution.
When more solvent is added to a solution to decrease its concentration, it is called dilution. Dilution involves reducing the concentration of solute particles within the solution by adding more solvent to increase the total volume.
A solution that has a small amount of solute dissolved in it.
Adding more solute to a solution will increase its concentration. Adding more solvent will only dilute it. Think of salt water. The salt is the solute, and water is the solvent. Add salt and it becomes a more concentrated solution. Add more water, and it is more dilute. Simple and easy once you think it through.
Adding more solute or adding more solvent
Adding solvent will make a solution more diluted. Think of it this way. Take water (solvent) and dissolve salt into it (solute). In order to dilute or increase the ratio of solvent to solute, you would add more water.
Adding more solute or more solvent can change a solution.
The molarity of a solution can be changed by adding more solute to increase the concentration or by adding more solvent to decrease the concentration.
Adding more solute or more solvent can change a solution.
Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.
The concentration of a solution can be changed by altering the amount of solute or solvent. Increasing the amount of solute while keeping the solvent constant raises the concentration, while adding more solvent dilutes the solution, reducing its concentration. Additionally, evaporation of the solvent can increase concentration, while dilution can be achieved by adding more solvent.
I presume from category that the question ask about the heat of dissolution. Assume the solvent and solution is at thermal equilibrium. Adding more solvent would yield change in interaction for non ideal solution and thus it could yield increase or decrease of temperature depend on the infinite heat of solution of the solute that we interested in. Adding more solvent would not yield temperature change for ideal solution.
By adding more solute to a fixed amount of solvent.
