The half way point (that is neutral pH) is 7. Above 7 is basic, and below 7 is acidic. Therefore a pH of 9 is a little basic.

Is ammnia an acid or a base?
"Ammonia", NH3, is a fairly strong base having at 1M concentration in aqueous solution a pH of 11.6
The pH of a 1.0 M aqueous solution of NaNO3 will be?
the pH will be 7 since this is a strong acid react with strong base
What happens to the pH of An aqueous solution if a few drops of acid are added to it?
If the solution is not basic then the pH will fall below 7
What does it mean to neutralize a solution and how can this be done?
to get a pH of 7(neutral pH) you need to add a base solution to an acid solution and vice versa until you eventually approach a pH of 7
What is the pH level in vineger?
Vinegar is a 10% aqueous solution of Acetic acid, a weak acid so its pH value is about 6.

How does an acid and base differ in meaning?
An acid solution has a pH under 7.A base solution has a pH over 7.

What is the pH schale used for?
pH is a measure of the acidity of an aqueous solution (a solution where water is the solvent). Specifically it is the negative logarithm of the molar concentration of hydrogen ions. A solution with a pH below 7 is acidic while one with a pH above 7 is basic or alkaline. A pH of 7 is neutral. Note that pH is not a measure of the strength of an acid or base, just how acidic or basic a solution is, which depends both on the strength and concentration of the acid/base.

Why would adding an acid or base lower the pH in a solution?
Adding an acid to a solution will lower it's Ph, but adding a base will raise it's Ph.
What is the acidic solution of pH?
Any aqueous solution will have a pH lower than 7.00 in order to be considered acidic.
What have a pH 4.5 acid base or neutral solution?
Anything with a pH less than 7 is an acid.
What is the pH difference between a strong acid and a weak acid n the pH scale?
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
When a solution of an acid reacts with a solution of a base hydronium ions react with hydroxide ions to form...?
Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule. Hydroxide ion, OH-, gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water. Combining H3O+ + OH- makes 2 H2O. In other words, an acid and a base combine to neutralize each other as water.
