Solved in 2 steps
- Sodas typically contain sugar, flavorings, coloring agents, and carbon dioxide dissolved in water. The best term to describe this mixture would be _____.Ions will flow _________ a concentration gradient. Around Up Down Parallel toThe pH scale shows availability of reactive hydrogen ions (H+) in a liquid. The scale is logarithmic, so milk has 10 times as many H+ ions as pure water, for a given volume. How many more H+ ions does soda pop have compared to pure water? Write the number only.
- Knowing that the solute concentration of blood is 0.9%, if you were to make 100ml of an intravenous (IV) fluid to make the blood concentration, you will need ______g of salt.The negative logarithm of the hydrogen ion concentration of an aqueous solution defines the of that solution. (answer case-sensitive) none of the above basic alkaline O pHA team of investigators is out on a boat on a lake on a marvelous,sunny summer day, and they are taking water samples fromvarious depths in the lake so as to construct a plot of dissolvedO2 concentration versus depth, similar to the plot in Figure 1.16.When the investigators bring up a water sample from a depthof 20 m, why is it imperative that they measure its dissolved O2concentration immediately, rather than letting it sit on the deckfor 5 minutes? (Hint: Look at Figure 22.2A.
