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.

Predict what will happen to the hydrogen ion concentration of an acidic solution if you add water to it?
Adding water dilutes the solution and therefore reduces the concentration of hydrogen ions.
Does adding water change the pH of a base?
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
Will the rusting of nails in a sodium chloride - water solution effect the reading off a voltmeter or ammeter?
An ammeter or a voltmeter gives the reading of the flow of current, which is due to the movements of ions. When a rusted nail is immersed in the solution it will add the no of ions into the solution. This will increase the ion concentration and therefore will change the reading of a voltmeter and ammeter.
To increase the concentration of a solution?
In order to increase the concentration of a solution, you must add more solute or remove some solvent. You can remove solvent through evaporation.
How do you dilute and concentrate a solution?
To dilute a solution, add water to it. To concentrate a solution, take water out of it.
How can the concentration of a solution change?
You add zinc to the solution and add 10% of what is left
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
Predict what will happen to the hydrogen ion concentration of an acidic solution if you add water to it?
Adding water dilutes the solution and therefore reduces the concentration of hydrogen ions.
How can you change the concentration of acid?
By diluting it with water or neutralising it with a base or alkaline
What would you do to increase or decrease the concentration of the nutrient solution?
The amount of water you add.
How you can make a solution from one concentration to another concentration?
You add zinc to the solution and add 10% of what is left
How do you precipitate soluble complex?
Add salt to the solution. Change the temperature of the solution. Let the solvent evaporate in increase the concentration of the soluble complex. Change the pH of the solution.
Does adding water change the pH of a base?
Yes. Ph is a measurement of the concentration of the hydronium ion [H+]. If you add more water you change the concentration.
To what volume whould i need to add water to the evaporated solution in problem 3 to get a solution with a concentration of 0.50M?
12.33333 times
How do you change the pH of a water solution?
Add an acid or a base to it.
What is infinite dilute solution?
Infinite dilution means such a large dilution so that when you add more solvent there is no change in concentration.
If you have a stock solution of 50ul at a concentration of 50 ul per ml and need a final concentration of 2 ul per ml how would you work this out?
You need to add the 50ul stock solution to 1200ul of distilled water to produce 1250ul of solution with a concentration of 2ul per ml.
