- The progress of the reaction between Iodine ions and potassium iodate(V) can be followed by withstanding samples of the reaction mixture at various times, quenching and then titrating with standard thiosulphate solution. The reaction equation is: I(aq) + IO3(aq) + 6H+(aq) + 4e ➡ I2(aq) + 3H2O(l) In one such experiment the following data were obtained. (see figure below) Determine the order of the reaction with respect to I(aq) and IO3(aq) ions Write the rate expression for the reaction.arrow_forwardWhich of these types of coprecipitation happens with greater probability when the particle growth of a single crystal happens very quickly, allowing a contaminant to be trapped within a particle?

- Z = [2(σP)/kT][8RT/pi(M)]1/2 2A. Based on the kinetic theory of gases, collision frequency is related to temperature, pressure and molecular cross section. Explain conceptually and based on the equation how the collision frequency is related to pressure. 2B. How does collision frequency relate to temperature. 2C. Sketch a plot of the relationship between collision frequency and temperature. Label your axes.arrow_forwardThe addition of a small amount of a salt, such as (NH4)2SO4, to a solution containing a charged protein increases the solubility of the protein in water. This observation is called the salting-in effect. However, the addition of large amounts of salt can decrease the solubility of the protein to such an extent that the protein precipitates from solution. This observation is called the salting-out effect and is used widely by biochemists to isolate and purify proteins. Consider the equilibrium PXν(s) ⇋ Pν+(aq) + ν X−(aq), where Pν+ is a polycationic protein of charge ν+ and X− is its counterion. Use Le Chatelier’s principle and the physical principles behind the Debye–Hückel theory to provide a molecular interpretation for the salting-in and salting-out effects.arrow_forwardA parcel of unsaturated air contains a mixture of dry air and water vapor. The specific humidity q of the air parcel is 12 g kg^−1. Recall that q = Mv / (Mv+Md),where Mv is the mass of the water vapor and Md is the mass of the dry air. This is equivalent to what we have been calling the fractional concentration of water vapor by mass. (a) If the air parcel is at a temperature T= 25◦C , what is the virtual temperature of the air parcel? (b) If the air parcel is at a temperature T= 25◦C and a pressure of 1000 hPa, what is the relative humidity of the air parcel? (c) What is the apparent molar mass of the air parcel?arrow_forward
- One technique for studying the energetics of protein structure is to monitor the struc- ture of the protein as a function of the osmotic pressure. In these experiments the os- motic pressure of the solution is varied by using polymers of different molecular weight and concentration. In an experiment poly(ethylene glycol) (PEG) with a molecular weight of 1000.0 g mol- was used. What concentration of PEG is needed to create an aqueous solution with an osmotic pressure of 150.0 Pa at 25°C? You may assume that PEG is uncharged and that it does not dissociate or aggregate.arrow_forwardNitric oxide reacts with hydrogen to release large amounts of chemiluminescence with the characteristics of the highly cytotoxic species.

- OSHA's Hazard Communication Standard requires chemical manufacturers to evaluate hazards relating to their products and provide a Safety Data Sheet in accordance to the Globally Harmonized System (GHS) in which the use of pictograms (see Figure 1) is required to communicate hazard information. Predict (with reasons) two (2) hazards related to each of the two activities below, and assign two (2) relevant pictograms listed in Figure 1 to each of the two activities. Activity 1: Removing diethyl ether (last opened in 2019) using a rotary evaporator. Activity 2: Using carbon monoxide gas as a reducing agent to reduce iron chloride. Figure 1.
