Which is the higher concentration H2SO4 Vs HCl?

Question

Accepted Answer

H2SO4 has a higher concentration than HCl.

Concentration is determined by the number of moles of solute per unit volume of solution.
H2SO4 has a higher molar mass than HCl, so the same volume of H2SO4 will contain more moles of solute.
Therefore, H2SO4 has a higher concentration than HCl.
For example, if we have 100 mL of 1 M H2SO4 and 100 mL of 1 M HCl, the H2SO4 solution will contain more moles of solute.

Accepted Answer

Generally, both Hydrochloric acid (HCl) and Sulfuric acid (H2SO4) are really strong acids compared to any other acids. However, HCl is stronger than H2SO4. This is mainly due to the difference in the basicity of both acids. Additionally, if we look at the pKa value HCl has a pKa of -6.3 and sulfuric acid has a pKa ~-3. What this means is that HCl is more acidic as it donates a proton easily.
