because it is hard
an alkali is much stronger than an acid because an acid has a PH of 1 and an alkali has a PH of 14.
an acid has a pH under 7 an alkali has a pH over 7
Borax is an alkali. it has a pH of 9.2
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.
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
Yes, because the pH is measured in a solution.

pH 11 is an alkali not an acid
Borax is an alkali. it has a pH of 9.2
No, the pH increases.

pH tests
Yes. The pH will increase.
Both an acid and an alkali can be strong or weak. These are 2 different things. A strong acid is an acid which has a low pH (pH 1 or 2 or 3) and a weak acid is an acid of pH about 5 or 6. Whereas a strong alkali is an alkali of pH 11, 12 while a weak alkali has a pH of about 7 or 8.
Sour milk is more acid than nomal milk. Lower pH = acid. Higher pH = alkali.
