Question

3. Wha t is the reason strong acids react with CaCOs (s) faster than weak acids? a. strong acids are more concentrated b. for solutions of equal concentrations, strong acids have more H3O ions c. strong acids form solids with insoluble ions d. weak acids react with water, and therefore don't react with the CaCOs (s) 4. How much of a 0.100 M NaOH solution is required to completely neutralize 10.0 mL of 0.200 M H2SO4? No calculations are necessary. a. the same volume as it would take to neutralize 10.0 mL of 0.200 M HCI b, twice the volume as it would take to neutralize 10.0 mL of 0.200 M HCI c. half the volume as it would take to neutralize 10.0 mL of 0.200 M HCI 5. How much of a 0.100 M NaOH solution is required to completely neutralize 10.0 mL of 0.200 M HC2H302? No calculations are necessary a. the same volume as it would take to neutralize 10.0 mL of 0.200 M HOI b. twice the volume as it would take to neutralize 10.0 mL of 0.200 M HCI c. half the volume as it would take to neutralize 10.0 mL of 0.200 M HCI d. much more volume than it would take to neutralize 10.0 mL of 0.200 M HCI, because 0 HC2H3O2 is a weak acid 0.200 M AgNO3. 0.200 M AgNO3. 6. Calculate the volume of 0.100 M NaCl that is needed to react completely with 50.0 mL of 7. Calculate the volume of 0.100 M CaCl2 that is needed to react completely with 50.0 mL of

Answer 1

Ans 3 : b) for solutions of equal concentrations , strong acids have more H3O+ ions

The acids are strong called when they can be completely ionized. The weak acids do not get ionized completely , due to which they have lesser concentration of hydronium (H3O+) ions in their solutions , even though their molarity is same as that of the strong acid.
