Why is H2SO4 more concentrated than HCl?
HCl is a stronger acid than H2SO4 because a proton more easily separates from chloride ion than from hydrogen sulphate ion and this is reflected in their dissociation constants. The lower the pKa value of an acid the stronger it is. The pKa values of HCl and H2SO4 are -6 and -3 , respectively.
Is Sulphuric acid and hydrochloric acid the same?
What is the difference between Sulphuric Acid and Hydrochloric Acid? HCl has one hydrogen atom and one chlorine atom. Sulfuric acid is H2SO4, , and has two hydrogen, one sulfur, and four oxygen atoms. Sulphuric acid is a diprotic acid whereas hydrochloric is a monoprotic acid.
What is the highest concentration of HCl?
Hydrochloric acid is produced in solutions up to 38\% HCl (concentrated grade). Higher concentrations up to just over 40\% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling.
Is Dil HCl stronger than conc HCl?
HCl acid ionises completely to H+ and Cl- ions (that is, about 100 out of 100 molecules donate their hydrogen ion). Hence, dilute HCl acid is stronger than highly concentrated acetic acid.
Why is H2SO4 a volatile acid?
Sulphuric acid has high boiling points and this is why it is used in the preparation of volatile acids such as Hydrochloric acid i.e. HCl, HNO3 and acetic acid from their salts.
Why is H2SO4 twice as acidic as HCl?
Thus, H2SO4 can consume twice as much base (alkali) as HCl of same molar concentration consumes. Sulphuric acid (H2SO4) is much more acidic than hydrochloric acid (HCl) of equal or same molar concentration. We can say it is twice as acidic as HCl acid.
What happens when hydrogen chloride and acetic acid are mixed together?
If we take hydrogen chloride and acetic acid of the same concentration, say one molar, then these produce different amounts of H+ ions. Acids that give rise to more H+ ions are said to be strong acids while the ones that give less H+ ions are said to be weak acids.
Why does H2SO4 react with NaOH to neutralize?
This is because H2SO4 is a dibasic acid, and one mole of it requires two moles of a monoacidic base like NaOH (alkali) for complete neutralisation. On the other hand, one mole HCl needs just one mole of NaOH for complete neutralisation, as it is monobasic.
What is the concentration of H3O+ in H2SO4?
When compared on the basis of the two other common ways of defining concentration, weight percent or normality, the H3O+ concentration in H2SO4 is 1/2 to 1/3 of that in HCl. So, if you as ambiguous question, you can’t expect anything other than ambiguous answers.
