Sabrina S: CHEMISTRy***********?
what would have the higher [H3O+] in water?
1.10.0M HCIO4 or 1.0M HCIO4?
2. 10.0M HCIO4 or 10.0M HNO2?
3. 1.0M HIO3 or1.0M H2SO3?
4. 1.0NH4^+ or 1.0M HF?
i picked 1.first one 2.first one 3.first one 4. second one

Your answers are correct.
1. the 10.0M solution is more concentrated, so it would have a higher [H3O+]
2. HClO4 is a stronger acid than HNO2, so it would have a higher [H3O+]
3. HIO3 is a stronger acid than H2SO3, so it would have a higher [H3O+]
4. HF is a stronger acid than NH4+, so it would have a higher [H3O+]
Answer by lappy1.first one – because the first one has a higher concentration. The higher the concentration, the more [H3O+]
2.first one – HCIO4 is a VERY strong acid
3.first one – HIO3 has a pKa value of 0.75 while H2SO3 has a value of 1.81. A lower pKa value means a higher concentration in H3O+
4. second one – ammonia is considered as a weak acid while HF is a strong oneAnswer by SHAWNA W
Thge strong acid would give 100% yield of H3O+ where weak acid would only give less than 10% H3O+. That being said….
1. with 10 molar you have more acid to donate hydrogen ions to water molecules, than with 1 molar sooo 10 molar is right
2. HClO4 is strong acid and HNO2 is weak so you’d have more H3O+ with HClO4.
and your right on 3 and 4
