either tap or distilled water was easy to change the pH, why?
this because it doesn't contains component of which will prevent the drastic change of pH, i.e. like that of those in buffer solution. thus even a small amount of acid or base added to tap water will cause a great pH change.
best answer?

You can easily change the pH of any water by adding sufficient acid or base. The amount you must add depends on the pH and quantity.

because the pH of water is 7, so it is in the middle of the pH scale and also has ions which are easily attracted to both polar and nonpolar ions...which changes the pH very easily either way (towards being an acid or a base)

rod has the right answer. It is because in some areas, the content of carbonates, bicarbonates and hydroxides is low. These polyatomic ions act as buffer systems, reducing the susceptiblity to pH change.
Easy way to visualize buffers and this problem is to imagine two samples of water, each with equal numbers of acid and base.
One million acids/one million bases in one sample, one acid/one base in the other sample. Both have neutral 7.0 pH, b/c both have equal numbers of acid/base.
When you add one acid to each sample, one sample will now have the ratio of 1million+1acid/1million base. Its pH will not change measurably.
However the other sample will now have the ratio 2acid/1base. Its pH will drop dramatically.

acid is easy to work with

Because water is a universal, isotonic solvent.
