On this scale, the strongest acid is 0 and the strongest alkali is 14. The universal indicator turns a different colour for all the numbers on the pH scale. WebbThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. tiny scanner vs tiny scanner pro
