Exp 7_C Post-Lab Chemical Equilibrium (10 pts/show all work) Determine if the following salts will be acidic, basic, or neutral. For each salt show the 1. balanced equation for ionization in H20 and Example: NaNO2(aq)> Na (aq)+ NO2 (aq) 2. how the ion products form which determine pH by producing OH or H30 Example: NO2(aq) +H20(1) <>HNO2(aq)+ OH (aq) If the salt is neutral give a brief explanation. a) LiF b) BaBr2 c) NHa d) CaSO3 ?) ???.
Which of the following compounds would make the best buffer at pH 7.5? Acetic acid, pKa= 4.76 N-tris(hydroxymethyl) methylglycine (Tricine), pKa = 8.15 N-2-hydroxyethylpiperazine-N’-ethansulfonic acid, pKa2= 7.6 Glycine, pKa2= 9.9 Tris(hydroxymethyl)aminomethane (Tris), pKa = 8.3 I believe 3 is the correct answer and therefore I am trying to answer the below question with this information. Using the answer that you selected from question 1 above: a. Explain how you would make the buffer starting with 1M HA and 1M A-...
