does a solution become less acidic or basic if more water is added?

Answer 1

If it is basic to start with, it will become less basic.

If it is acidic to start with, it will become less acidic.

In both cases, you're diluting the solution.

Answer 2

It's concentration decreases.

If initially, you have (speaking in very basic and non-scientific terms), say 5 molecules of acid in 100 molecules of water, the ratio is 5:100.

Then if you add 100 more molecules of water, you'll have 5 molecules of acid in 200 molecules of water. So logically, your solution is less acidic.

If this is a dilution problem you're working on, there's a simple formula for it: concentration of solution 1 x volume of solution 1 = conc. of solution 2 x volume of solution 2. If you have 3 knowns and only one unknown, you should be able to find the unknown with simple algebra.

As for the units used for concentration, you can use M or nM or anything that is of a Molar concentration, as long as conc. 1 and conc. 2 have the same units. The same applies for volume units.

Answer 3

That depends on what solution you are adding the water to.

Water is neutral (pH of 7) so if you start out with an acidic solution, like, H2SO4, the water will make it less acidic.

If you start out with a basic solution, like, NaOH, the water will make it less basic.

Answer 4

Yes, a solution will become less acidic or basic, if water is added. pH is the measurement of how acid or basic somthing is. pH is the log of the molar concentration of the hydrogen. And if the molarity is changed, becasue more solution, aka water, is added, then the pH will go down.

Answer 5

haha it depends on which one it was, since water i believe has a PH of 7 so is in the middle between acid and bases

Answer 6

When you add water to whatever solution it will probably bring the solution closer to the pH of water(unless they don't react like oil.)

Answer 7

its diluted to neutrel
