It will all depend on the amount of solution and the amount of acid that you add. It will move the pH closer to 7. If the amount of solution is rather small, the pH will move further towards the acid side.
The pH will increase.
Adding a base to any solution will increase the pH.
It should not change, as the equilibria in the buffer will move to absorb the hydroxide ions.
pH will explode into the air
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
The weak acid becomes in unionized form
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).
Concentrated solution because it is a strong solution. It has a large amount of solute which fits the definition of concentrated solution.
a water solution of a strong acid is what?
This leads to neutral water by H+ + OH- --> H2O and neutral salt solution when added in equavalent amounts, BUT it is NOT a buffered solution.
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
you will die
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
In a weak solution, fizzing. In a very strong solution - run away.
The weak acid becomes in unionized form
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
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).
Concentrated solution because it is a strong solution. It has a large amount of solute which fits the definition of concentrated solution.
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
a water solution of a strong acid is what?
The final pH of the mixture will depend on how much of the strong acid you add. The initial amount of acid will neutralize the alkaline solution, and if there is enough of the strong acid, the final pH will then become acidic, i.e. pH < 7.
