Question
The following pictures represent solutions of a weak base B that may also contain the chloride salt BH+C1- (Figure 1) (Cl- ions and solvent water Which solution has the lowest pH? Which has the largest percent dissociation of B? Write balanced net ionic equations for the neutralization of equal molar amounts of the following acids and bases. Indicate whether the pH after neutralization is greater than, equal to, or less than 7. Values of Ka and Kb are listed in Appendix C in the textbook. Write balanced net ionic equation for the neutralization of equal molar amounts of HBr and NH3 Express your answer as a net ionic equation. Identity all of the phases in your answer. Write balanced net ionic equations for the neutralization of equal molar amounts of the following acids and bases. Indicate whether the pH after neutralization is greater than, equal to, or less than 7. Values of Ka and Kb are listed in Appendix C in the textbook. Write balanced net ionic equation for the neutralization of equal molar amounts of KOH and HCIO4 Express your answer as a net ionic equation. Identify all of the phases in your answer. The pH after neutralization is:Explanation / Answer
1>lowest pH is solution (1) as B is weak base its conjugate acid BH+ is a strong acid
2> again(1)
3>
KOH --> K+ + OH- ...................................(1)
HClO4 --> H+ + ClO4-.................................(2)
_______________________________________________
(1) + (2) = net reaction
K+OH- + H+ClO4- --> K+CO4l- + H+OH-
4>pH is greater than 7 as KOH is strong base and acid is weak
