Urea water solution is neutral.
Adding an acid the pH decrease.
OK, so how do we neutralise an acid. Answer: with a base. Because water can exist in the following state: H2O <_> H+ + OH- This means that water exists as both an acid and a base, and at pH 7, water can neutralise the base. Obviously bases of lower pH may require a basic solution to clean up, but for weak acids a watered or damp cloth will do the trick.
It could be anything. If you have acid and neutralise it with a base, will get a solution which is pH 7 but it would not be water.
While I can't find a specific pH value - it is certainly acidic - as it's used to 'neutralise' alkaline soil.
When anything is neutralized, the pH value moves closer to 7. In addition, when a weak acid is being neutralized, a buffer is also being formed, until all the weak acid has been converted to the salt.
pH = 7.00 at 25oC

An acid! :)
Under 5,5.
alkali bases pH greater than 7
Acid - you add lemon juice to it.
alkili is the best
It is an alkanolamine, used to neutralise the pH in cosmetic solutions/suspensions.
Water is slightly acidic (around pH 5.6),a lot of countries/places,such as Sweden, use calcium oxide to neutralise bodies of water affected by acid rain.
add a solution to it that has a low pH level (an acid) to neutralise it, or bring it down slightly. What is it that has the high pH?
