Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
If the volumes in the buret and the flask are identical and the concentration of the acid in the buret is 0.250 M, what is the concentration of the base in the flask.
A balloon filled with helium gas has a volume of 500 mL at pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm.
Estimate Delta G or this reaction at each of the following temperatures. (Assume that Delta H and Delta S do not change too much within the given temperature range.)
Buffering Action of Proteins, We did this experiment in class but I want to see if the results seem reasonable and, if so, why they were not more varied.
A second-order reaction of the type A+2Bâ†'P was carried out in a solution that was initially 0.050 mol dmâˆ'3 in A and 0.030 mol dmâˆ'3 in B. After 1.0 h the concentration of A had fallen to 0.010 mol dmâ
