Anything with a pH higher than 7 is a base, lower than 7 is acidic.
If something is alkalic, it is higher that 7 on the pH scale
The strength of an acid and alkali is shown using the pH scale which goes from 0 to 14 . pH number of acid is less than 7. and pH number of alkali is greater than 7. that's why the smaller the number the stronger the acid and the larger the number the stronger the alkali. so pH of weak acid is 6 and pH of strong alkali is 14 because if the smaller number shows the stronger acid, the larger number shows the weaker acid. And as larger number shows strong alkali, the pH scale is from 0 to 14; so 14 shows stronger alkali.
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.
If something is alkalic, it is higher that 7 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.
