13. The actual concentration of the solution turned out to be .447M when we account for the added volume of the solvent when mixed with the solute. (MW of sucrose is 342g) % error = │.500-.447│ ---------------- x 100 = 11.85 % .447 14. The term pH comes from potential of hydrogen and is the logarithm reciprocal of the hydrogen ion concentration in a solution in grams of atoms per liter. It provides a measure on a scale from 1 to 14. A buffer is a solution that resists changes in pH. This would be beneficial in the body in the blood because any slight changes in ph would become detrimental to the body. This is why a buffer would help the body resist any change in ph. 15. A solution with the ph of 7 would have a concentration of 10^-7 H+ ions per liter. A solution with the ph of 8 would have a concentration of 10^-8 H+. Because the solution with the ph of 7 has more H+ ions, it would be the more acidic solution of the two. 16.-17. ?
