Water is already neutral.
water your soil
Pure water is always neutral.
No
Urea water solution is neutral.
No
Yes, bases neutralize acids by accepting their hydrogen ions to form water and a salt. This reaction reduces the acidity of the solution.
Sodium Bicarbonate, also known as baking soda
Only when they exactly neutralise one another.
Use the Mega-Plasma Blaster, it never fails to neutralise with extreme prejudice.
A salt and water and if the base is a metal carbonate, carbon dioxide is also formed
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.
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.
