On ly mixing strong acids with strong bases or weak acids with weak bases will be giving water or some other substances with the same concentration of ions
The concentration of ions in 10 is not twice as high as in 5
You get a salt (not necessarily what we think of as "salt," which is NaCl) and water. If you started out with too much acid, there will still be some acid; if you started out with too much base, there will still be some base. If the proportions are just right, you'll get just salt and water.
Add a strong base to strong acid and you will neutralize it. Similarly, add a strong acid to a strong base and it will be neutralized. For example:- HCl + NaOH ----> NaCl + H2O You add a strong base to a strong acid and get a neutral salt and water.
If you add the same quantity of an acid and a base it will become neutral.i.e forms salt and water
Add a strong base to neutralize the strong acid
Buffers contain both one weak acid and its coupled weak base, that can not react with each other (they are a so-called conjugated system). When you add strong acid it will react with the base part of this buffer, when strong base (hydroxide) is added it will react with the acid.
If you have an acid of unknown strength, you add Universal Indicator & add drops of a base. Count the drops of the base until the solution turns green (neutral) This should tell you how strong the acid is. This can also be done the other way (with a base of unknown strength & adding an acid) Does that make sense?

The pH remain unchanged.

If the pH is higher than she wants it to be, she gotta add acid. If it too low, add base. :p Apex
The resist pH change in the following way: If you add a strong acid to the buffer solution, the conjugate base gets protonated, but the pH is not significantly changed. If you add a strong base to the buffer, the conjugate acid gets deprotonated, and again the pH is not changed very much. If you only had one component (let's say just the conjugate base), then it would not be able to resist change in pH if you added a strong base to the solution (although it would still counteract the affect of added acid).
They neutralise each other, assuming you neutralise a volume of acid with a base of the same molarity they completely cancel each other out leaving water and a salt. The salt differs depending on the acid and base used.
If it is an acid then add a base until the pH level becomes 7, which is neutral. If it is a base, add acid until the pH is seven.
