Document Summary

For weak acids alone in water: pz= -logz. [h+][ho-] = 1. 00 x 10-14 ph + poh = 14. Kakb= 1. 00 x 10-14 for conjugate acid/base pair. If 10 ml of 0. 10 m hcl is added to this buffer solution, the ph of the solution will. Hcl reacts with the present in the solution. slightly because the: increase, ch3nh3, increase, ch3nh2, decrease, ch3nh2, decrease, ch3nh3. 1: consider a solution containing 0. 80 m naf and 0. 80 m hf. Equivalence point (when equal moles of each have been added: hclo4 + naf, hno3 + koh, nh4cl + naoh, hf + naoh, none of the above. 2no (g) + cl2 (g) 2nocl (g) s = -117 j/mol k. C (s) + h2o (g) co (g) + h2 (g) Reaction 3: h2o(l) h2o(s) at 25 c: reaction 1 only, reaction 2 only, reaction 3 only, reactions 1 and 2 only, reactions 1 and 3 only. A (aq) + b (aq) c (g) + d (aq)
