By titration, it is found that 87.1 mL of 0.153 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the concentration of the HCl solution. (HCI) In the acid reaction, classify each substance as the stronger acid, weaker acid, stronger base, or weaker base. A table of acids and their conjugate bases, listed by relative strength, may be helpful. HCN + HCO3 CN + H,CO Answer Bank weaker acid stronger base stronger acid weaker base Which direction does...

The net-ionic equation for an acid base reaction involves transfer of a proton (H ion) from the acid to the base. The products represent the conjugate base and acid of the reacting acid and base. The net-ionic equation for this system is shown here. HF-CN= F-HCN If you compare two acids and one is stronger than the other, how do the strengths of their conjugate bases compare? It is given that HF is the stronger acid. Which is the stronger...
