pertuint UI (TI/III) CONCentration. Step 5. Put exactly 1 cup (or 237 mL) of distilled water into the 2-cup measuring cup. Place two level teaspoons of table salt in the measuring cup. Mix thoroughly. How does this compare to the looks of Step 1 above? Where is the level of the solution now? Do you think it is more dilute or less dilute than Step 1 above? Explain your answer. Remember that one teaspoon of table salt (NaCl) weighs approximately 4.0 grams. Also, pecause the density of water at room temperature is 1.0 g/mL, then if you used 237 mL of water 1 cup), then that is 237 grams of water. Using the formula for mass percent (m/m) = (mass of solute (g)/ mass of solute + mass of solvent) x 100%, calculate the mass percent of your solution you made in Step 5. Show your calculations.

Addition of water to concentrated sulfuric acid is dangerous because it generates enough heat to boil the water, causing it to spatter out of the container. For this reason, chemists remember to add acid to water. In a dilution experiment, we calculate the amount of the more concentrated solution that must be measured out. If we place this concentrated solution (Figure 4.7) in the volumetric flask first, then dilute with water, we violate the caution Add acid to water. Describe a safer variation on the method shown in Figure 4.7 that allows the quantitative dilution of concentrated sulfuric acid. Figure 4.7 Preparing a dilute solution from a concentrated solution. (a) Draw the concentrated solution into a pipet to a level just above the calibration mark. (b) Allow the liquid to settle down to the calibration line. Touch the tip of the pipet to the side of the container to remove any extra liquid. (c) Transfer this solution to a volumetric flask. Again touch the pipet to the wall of the flask to ensure complete transfer, but do not blow out the pipet because it is calibrated for a small amount of liquid to remain in the tip. (d) Dilute to the mark with solvent. Frequently, especially with concentrated acids, it is best to have some solvent present in the volumetric flask before you add the concentrated sample.
