FO 19: Describe how a buffer reacts to the addition of strong acids and bases. You made 1.0 L of a buffer using 0.24 M sodium dihydrogen phosphate, NaH$_2$PO$_4$, pKa 7.21 and 0.18 M sodium hydrogen phosphate, Na$_2$HPO$_4$. (a) Write a net ionic equation for the proton-transfer that happens in the buffer when you add 0.25 moles CsOH. Acid (b) What happens to the pH of the solution when you add 0.25 moles CsOH? (c) Is it still a buffer? FO 20: Draw predominant structures at a given pH. You've prepared 3 buffered solutions containing L- arginine. Each buffer is at a different pH. Draw the predominant form of L-arginine at each pH. pKa 12.48 NH$_2$ $\qquad\qquad\text{O}$ H$_2$N$ $\qquad\text{NH}$ $\qquad$OH pKa 2.17 $\qquad\qquad\text{H}$ L-arginine $\qquad\qquad\text{NH}_3$ pKa 9.04 pH 4.5 buffer pH 7.2 buffer pH 10.0 buffer 2

True/False ____ 9. A favorable cost variance occurs when actual cost is less than budgeted cost at actual volumes. ____ 10. The budgeted volume of production is based on the sum of (1) the expected sales volume and (2) the desired ending inventory, less (3) the estimated beginning inventory. ____ 11. One reason not to depend solely on historical records to set standards is that there may be inefficiencies contained in past costs. ____ 12. The difference between the standard cost of a product and its actual cost is called a variance. ____ 13. If yearly insurance premiums are increased, this change in fixed costs will result in an increase in the break-even point. ____ 14. After the sales budget is prepared, the production budget is normally prepared next. ____ 15. The variance from standard for factory overhead cost resulting from operating at a level above or below 100% of normal capacity is termed volume variance. ____ 16. Companies with large amounts of fixed costs will generally have a high operating leverage.
