Which would be the weakest acid?Question 9Answera.H2SO4b.HCOOHc.HFd.H3PO4Clear my choice
Solution
The acidity of a substance is determined by its pKa value. The higher the pKa value, the weaker the acid. Here are the pKa values for the given acids:
a. H2SO4: -3 b. HCOOH (Formic acid): 3.75 c. HF: 3.2 d. H3PO4 (Phosphoric acid): 2.15
From these values, we can see that HCOOH (Formic acid) has the highest pKa value, making it the weakest acid among the given options.
