One of the possible consequences of climate change is anincrease in the temperature of ocean water. The oceansserve 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 lesssimilarly to other gases in this respect?(b) What are the implications of this figure for the problemof climate change?
An excess amount of Ba(NO3)2 was added to 2 liters of water at 25 oC until the solution is saturated. Because Ba(NO3)2 is only slightly soluble in water, the excess Ba(NO3)2 was filtered out to get a solid-free mixture. The proponents of the experiment thought about using the concept of colligative properties, specifically boiling point elevation, to determine Ksp. It was observed in their experiments that the solution boils at 100.15 deg C. Kb of water = 0.51 K-kg/mol. Barium nitrate dissociates using: Solve the ff: a) Amount of Ba(NO3)2 dissolved in grams. MW of Ba(NO3)2 = 261.3 g/molb) Solubility product, Kspc) Vapor pressure of the solution in kPa
A batch of 500 ?? of ??? dissolves in water to form a saturated solution at 350 ? (77 °?) where the solubility is 30% by weight of ??? in water. The solution cools at 293 ? (20 °?) at which the solubility is 25.4% by weight. Determine the number of crystals obtained if 3.5% of the original water evaporates on cooling. Also, determine the capacity of the container in which this solution is cooled if it is 1.20 times the volume of the solution. The density of the solution is ???? ??/??
The rise in atmospheric carbon dioxide results in higher concentrations of dissolved carbon dioxide in natural waters. Use Henry's law and the data as given to calculate the solubility of CO2 in water at 25 °c when its partial pressure is (a) 3.8 kPa. (b) 50.0 kPa.
Can you form a homogenous solution between ionic compounds like LiCl and vegetable oil? Why or why not? Explain your reasoning using thermodynamic equations or values to support your answer (hint: think of ΔHsolution = ΔHsolute + ΔHsolvent + ΔHmixture and the types of IMFs that can form between solute-solute, solvent-solvent, and solute-solvent particles. Also, it would be helpful to compare IMFs between solute-solute, solvent-solvent, and solute-solvent particles for water and vegetable oil as a solvent.
For the calculation of the solubility c of a gas in a solvent, it is often convenient to use the expression c = Kp, where K is the Henry’s law constant. Breathing air at high pressures, such as in scuba diving, results in an increased concentration of dissolved nitrogen. The Henry’s law constant for the solubility of nitrogen is 0.18 μg/(g H2O atm). What mass of nitrogen is dissolved in 100 g of water saturated with air at 4.0 atm and 20 °C? Compare your answer to that for 100 g of water saturated with air at 1.0 atm. (Air is 78.08 mol per cent N2.) If nitrogen is four times as soluble in fatty tissues as in water, what is the increase in nitrogen concentration in fatty tissue in going from 1 atm to 4 atm?
You have a solution that contains 4.0g of oxalic acid dissolved in 100ml of water. this solution is placed in a separatory funnel, and then 100ml of diethyl ether is added to the separatory funnel and an extraction is performed. (Diethyl ether and water are immiscible solvents.) Use the following constant to calculate how much oxalic acid is in each solvent after extraction. Solubility of Oxalic acid in water=9.5g/100ml Solubility of Oxalic acid in ether=16.9g/100ml
We can calculate the amount of freezing point depression that will occur using the following equation: ΔT = ikfm where ΔT is the amount of the change in the freezing point, i is the number of particles dissolved, kf is a constant (different for each solvent), and m is the concentration of dissolved material. This concentration has units of mol per kg solvent. With this in mind, let's calculate the amount of depression that will occur when 5 g of sugar (sucrose) is dissolved into 0.250 kg of water. Remember when sucrose dissolves in water remains as one particle. The kf for water is 0.512 0C/m. Report your answer with two decimal points and no units.
A solution of common salt in water is prepared by adding 50kg of salt to 200kg of water tomake a liquid density of 1250kg/m3. Calculate the concentration of salt in this solution as a: i) Weight(w/w)fraction (Ans: weight fraction 20%)
In biological systems, a FACILITATED transport process is a form of _______ transport, where an important chemical component moves with the aid of a channel or similar structure. According to the course lectures, Zoom sessions, course lecture notes, and/or assigned course readings, one specific example of a facilitated transport structure in the cell membrane is _________ , which aids in the movement of a particular chemical component called __________. A PASSIVE transport (or diffusion) process is one in which an important chemical component moves from where it is in concentration to where it is ________ in concentration. Meanwhile, an ACTIVE transport process is one in which an important chemical component is moved from where it is in concentration, to where it is _________ in concentration. Between passive and active transport, it is _________ transport that requires energy (of some form) to occur
A water carbonating plant is available for use in the home and operates by providing carbon dioxide at 5.0 atm. Estimate the molal concentration, m (in mol/kg), of the soda water it produces. The Henry's law constant for CO2 in water at 25 °C is 1650 atm. Use the following representation of Henry' law: PB = xBKB where PB is the vapor pressure of the solute; xB is the mole fraction of the solute (mole per mole); and KB is the proportionality constant.
