Molarity

[Abhinav Amanaganti 3K]

Can a solvent ever increase the molarity of a solution by increasing the amount of solute? Or do solvents never contain solute?

[Alison King 3L]

Solutions have solvent and solute. Solvent is the thing the solute is dissolved in (Ex: water). Solute is dissolved in the solvent (ex: salt). The molarity of a solution can be increased through increasing solute, since M = mol/L, increasing the mols of the solute will increase the molarity.

I would have to say no. If a solvent contains solute in any significant amount (enough to change the concentration), it becomes a solution. Tap water, for example, is a solution.

The amount of solute/solvent in a solution directly effects concentration.
More solvent = decreases the concentration
More solute = increases the concentration

[Ashrita Singh 2F]

No, once a solvent is combined with a solute, it is a solution.

[Sidharth Paparaju 3B]

No. If I put 1 mol of salt in 2 L of water, then I have a solution of 0.5 M that has 1 mol of salt. If I add another L of water, then I have 1/3 M, but I still have 1 mol of salt since no salt was added.

[Wendy Zhao 1I]

No, because molarity=mole of solute/volume of solution. Adding solvent only increases volume of solution without increasing mole of solute, so the molarity always decreases.

[Rainy Liu Ruoshui_2K]

No, because molarity and the volume of the solution are inversely proportional. Adding solvent increases the volume and decreases the molarity.
