2-4 ph
The pH become lower.

alkaline is the other thing apart from acid that can make the PH of a quench water decrease.
PH levels make sure water is not to acid.
Lemonade has a pH of about 2 or 3. Acidic substances have pH's below 7 and while bases have pH's above 7. Pure water (deionized) has a pH of 7.0. (Tap water is generally slightly acidic with a pH of ~6.5).
yes it adds alkaline- well it depends what pH water you get, if its more acidic it'll make the pH change but so will alkaline.
Absorbed carbon dioxide has an effect of lowering the pH of water.
Diluting with water will make this solution more neutral, meaning it will slowly increase to 7, which is the pH value of pure water used for this dilution.
the higher the acidic pH of the water will make the bean seed grow less
You can't. To make your water pH 0, you need pure H+ ions, which is impossible since water also includes oxygene. But you can make it closer to 0 by adding an acid. You can for instance use vinegar or lemon juice.
I will assume you are asking about the pH of pure water if pKw is 14.26. The relationship between pH, pOH, and pKw is as follows: pH + pOH = pKw. If it is pure, neutral water (no acids or bases present), then pH = pOH, so: pH + pOH = 14.26 2(pH) = 14.26 pH = pOH = 7.13
