The pH of an alkali is typically above 7 on the pH scale. Alkalis have a pH greater than 7 due to their ability to donate OH- ions in solution, making them basic substances.
The pH scale of the strongest alkali is typically around 14. Examples of strong alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which can produce a highly alkaline solution with a pH of 14.
Saliva is slightly alkaline, with a pH range of around 6.2 to 7.6. This means it tends to be more on the basic (alkaline) side of the pH scale.
Pure water is neutral, neither an acid nor an alkali. Its pH is around 7, which is considered neutral on the pH scale.
Apples juice is acidic.
No, it is an alkali according to the pH scale or pH indicator.
its an alkali, the other side of the pH scale you numpty;)
The pH Scale.
A strong alkali :)
A soluble base is an alkali, so above 7 on the pH scale.
An alkaline solution has a pH over 7,00.
The pH of an alkali is typically above 7 on the pH scale. Alkalis have a pH greater than 7 due to their ability to donate OH- ions in solution, making them basic substances.
how acidic alkali or neutral a substance is.

Pure water is neutral, neither an acid nor an alkali. Its pH is around 7, which is considered neutral on the pH scale.
The pH of water changes after a reaction with an alkali metal because the metal reacts with water to produce hydroxide ions, increasing the concentration of hydroxide ions in the solution and making it more basic. This leads to a shift in the pH towards the alkaline side of the pH scale.
