Page 3 of 3 For each problem, show your work. 1. Complete Table 2 below: Place Salinity (ppt) Salton Sea 44 California Great Salt Lake 280 Utah Mono Lake 210 California Pacific Ocean 87 Table 2: Salinity of Famous Places Amount of salt in 1 liter (grams) 2. How many grams of salt are in 2 liters of seawater that has a salinity of 36 ppt? Amount of pure water in 1 liter (grams) 3. A one-liter sample of seawater contains 10 grams of salt. What is the salinity of this sample? 4. You want to make a salty solution that has the same salinity as the Dead Sea. The salinity of the Dead Sea is 210 ppt. Write a recipe for how you would make 2 liters of this solution. 5. Five kilograms of seawater contains 30 grams of salt. What is the salinity of the volume of seawater? 6. You measure the salinity of a seawater sample to be 30 ppt. How many grams of salt are in this sample if the mass is 1.5 kilograms? 7. A solution has 2 grams of a substance in 1,000,000 grams of solution. Would you describe the concentration of the substance in solution as 2 parts per million or parts per billion? 8. A solution has 5 grams of a substance in 1,000,000,000 grams of solution. Would you describe the concentration of the substance as 5 ppb or 5 ppm? 9. Menthol is a substance that tastes sweet and minty and causes a cooling effect on your tongue. The taste threshold for menthol is 400 ppb. Could you taste menthol if there were 400 milligrams in 1,000,000 grams of menthol solution? Could you taste menthol if there were 400 milligrams in 1000 liters of menthol solution? 10. Above-ground pipelines are used to transport natural gas, an important energy source. Gas leaks are potential problems with the pipelines. German Shepherd dogs can be trained to detect the gas leaks. The dogs sniff along the pipeline and then indicate a leak by perking up their ears or pawing the ground. The most sensitive electronic devices can detect gas leaks as low as 50 ppm. A German Shepherd can detect a gas leak as low as 1 ppb. How many times more sensitive is the dog as compared to the electronic device? 21.2
Name: Date: 21.3 Calculating pH The pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. The pH scale, which ranges from 0 to 14, provides a tool to assess the degree to which a solution is acidic or basic. As you may remember, solutions with low pH values are very acidic and contain high concentrations of hydrogen ions. Why does a low pH value mean a high concentration of H+? The answer has to do with what pH means mathematically. In this skill sheet, we will examine how pH values are calculated. How do you calculate pH? The pH value for any solution is equal to the negative logarithm of the hydrogen ion (H+) concentration in that solution. The formula is written this way: pH – log H + = [ ] Concentration of hydrogen ions is implied by placing brackets (“[ ]”) around H+. A term used by scientists to describe the concentration of a substance in a solution is molarity. Molarity (M) means how many moles of a substance are present in a given volume of solution. For hydrogen ions in solutions, the concentration generally ranges from 10 to 10 –14 M. The larger the molarity, the greater the concentration of H+ in the solution. If a solution had a H + concentration of 10 –3 M, the corresponding pH value would be: pH – log 10 3 – = [ ] 10 pH 10 3 – – [ ] For a solution with an H + concentration of 10 –5 M, the corresponding pH value would be: pH = = pH = 3 – [ – 3] pH – log 10 5 – = [ ] 10 pH pH = = pH = 5 10 5 – – [ ] – [ – 5] The first solution has a higher H + concentration than the second solution (10 –3 M versus 10 –5 M); however, its pH value is a smaller number. Strong acids have small pH values. Larger pH values (like 14) have lower concentrations of H + , and the solutions represent weaker acids. 21.3
