Calculate the H2O+ concentration for each pH. pH = 11 [H,0"]= pH = 2 [H,0"]= pH=7 [H,0"]=
Calculate (a) the pH and (b) the concentration of acetate ion resulting from the mixture of400 ml of 0.1 M formic acid and 100 ml 0.1 M sodium acetate. This mixture constitutes a two component buffer. Such buffers are frequently used in the laboratory. More to the point, cell and body fluids contain more than one buffer system.
Calculate the pH for each H+ concentration. [H+] = 1 x 10-6 M pH = [H+] = 0.001 M pH = [H+] = 1 x 10-11 M pH =
