Chapter 18, Problem 71a

One of the possible consequences of climate change is an increase in the temperature of ocean water. The oceans serve as a 'sink' for CO2 by dissolving large amounts of it.

(a) The figure below shows the solubility of CO2 in water as a function of temperature. Does CO2 behave more or less similarly to other gases in this respect?

Welcome back everyone in this example, we have the graph below which shows the soluble itty of sulfur dioxide and water at varying temperatures. Does the sulfur sulfur dioxide behave more or less similar to other gasses in this respect. So what we are going to want to refer to is our sorry ability curve. So solu ability curb of gasses and water and we can ultimately just fill in for what we see here in our given diagram, which only shows our ability curb of sulfur dioxide where we see begins at the salt ability of about 200 will say 45 g or sorry milligrams per 100 g of water and it decreases As we get higher in temperature to about 40°C. Now, if we think of other gasses for example, we can think of methane, we should recall that methane has a soluble itty curb, that follows a similar trend starting from high Celje bility and decreasing insoluble itty as we continue down to higher temperatures or across higher temperatures. We also can think of another gas being oxygen gas, where we will see oxygen gas has a slightly lower salt ability than methane gas. However, it still does decrease in cell viability as temperatures increase. And thinking of a third gas, we can think of carbon monoxide, which has an even lower Selya bility than oxygen gas, but also follows the trend of decreasing in Celje bility as temperatures increase. So this is for carbon monoxide gas and now thinking of one more gas, we can think of helium gas, which we see starts out at a much lower sorry ability compared to all of our gas is so far so even below our cell ability of sulfur dioxide but also generally follows the trend of decreasing in cell viability as temperatures increase. So that is for helium. And so based on this trend that we've outlined, we're going to agree that based on our given diagram, sulfur dioxide generally does follow the trend of decreasing in Celje bility as temperatures are increasing. And so we would say for our final answer that the trend in change of sulfur dioxide sell ability as temperature increases is the same as most other gasses. And this entire statement would be our final answer to complete this example. I hope everything I reviewed was clear. If you have any questions, please leave them down below and I'll see everyone in the next practice video.
