Answer:

The answer to your question is   Ka = 1.99 x 10⁻⁵

Explanation:

Data

pKa = 4.7

Ka = ?

Ka is the acid dissociation constant, it measures the dissociation of n acid in aqueous solution. It does not have units.

pKa is a value that helps to indicate the strength of an acid.

Formula

pKa = -log Ka

-Substitution

4.7 = -log Ka

-Solve for Ka

    -4.7 = log Ka

  antilog (-4.7) = Ka

-Result

  Ka = 1.99 x 10⁻⁵
