If 11.90 mL of 0.775 M KOH is required to titrate the unknown acid to the equivalence point, what is the concentration of the unknown acid?


Expert Answer

Step 1

The reaction between an acid and a base to make a salt and water is a common reaction. An acid-base reactions are so prevalent , because they are often used in the  lab to determine quantitative amounts of one or the other.
