Question 1 of 11
1. Question
Given the initial conditions of concentrated blood as in Figure 5 below, find the final pH, species concentrations, and the number of molecules for each species upon dilution to 1.0 L. Obviously, the blood is treated as water, which means ignore other ingredients of blood.
Figure 5: Given the initial conditions of concentrated blood, find the values for the same properties at Vfinal=1.0 L. Upload a screenshot or a text file of your answer

Question 4 of 11
4. Question
Given the concentration of hydronium (H3O+) ion and the hydroxide (OH−) ion as in Figure 8, what will be pH? Write down the number of water molecules, the number of hydronium (H3O+) ions, and the number of hydroxide (OH−) ion. Use both applet and the procedure outlined in this module (see equations 4 through 14).
