Adding a base to a solution would?
reduce the H+ concentration

Which statement best describes the process of making a solution by diluting a stock solution?
You can dilute by adding distilled water. When diluting, be sure to add the solution to water several times instead of adding water to the solution (especially if it is highly concentrated).
How can a solution be made more concerntrated and less concerntrated?
A solution's concentration is a measure of solute/solvent. Solute is the thing to be mixed in (i.e. salt in salt water) and solvent is the medium, usually liquid, for the solute to be mixed in (i.e. the water in salt water). Therefore, increasing the ratio of solute to solvent would increase the concentration. This could be done by adding more solute, or removing the solvent (i.e. going back to the salt water, adding more salt, or evaporating water would increase the concentration) The converse of this is also true to decrease the concentration.
What would decrease the rate of solution when dissolving a solid in water?
By irritating a solution, increasing the concentration of the solute, by increasing the temperature

What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.

If you were making iced tea from a mix (adding powdered iced tea to water) and it tasted too strong how would you describe this solution qualitatively in terms of concentration?
This solution is too concentrated for your taste.
If more solvent is added to a solution?
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.
What is it called when water molecules move from a low concentration of a solutes to a high concentration of solutes?
Osmosis. A solution with a low concentration of solutes would have a higher concentration of water than a solution with a high concentration of solutes. So in this case, water is moving from a higher concentration of water to a lower concentration of water, which is osmosis.

Which would you expect to have a greater influence on the effect of a solution in natural water concentration or solubility?
The concentration; to prepare a solution the compound must have a solubility.
