pH = 7.00 at 25oC
Adding an acid the pH decrease.
it mostly ranges form 8 to 10 on the ph scale because it needs to be an alkali to neutralise the acid in the stomach
alkali bases pH greater than 7
Acid - you add lemon juice to it.
An acid would be on the left side of a pH scale
Acid reduces Ph So by adding potash you will neutralise the acid and regain the correct Ph
The Ph scale does not have colours.
It is an acid. Acids have a pH below 7 and can neutralize alkalis by reacting with them to form water and a salt.
0 - 6.9 The lower the pH number the higher the concentration of hydronium ions and higher the strength of acid
The pH scale.
You place an acid onto the wound to neutralise the alkaline bee sting.
An acid is below 7 on the pH scale and bases are above 7 on the pH scale. An acid can be a hydrogen donor, and a base is a hydrogen acceptor.
