Question 1 1. A college student calculated the carbohydrate contents of an unopened refrigerated soft drink instead of one that had remained opened up at room temperature as instructed. What effect would the distinction in temperature and also the gas bubbles have actually on the determination of sugar contents in the soft drink? it is in very details in her answer, explaining why the sugar content will certainly be artificially high or low once this error is made. 0 Words inspect Answer Next>
3. Pure water is carbonated by way of bubbling gas CO2 with it. Then it is bottled. A. If the air room in the bottle above the water consists of only CO2 in ~ a push of 2 atm, what is the equilibrium pH that the carbonated water? Use precise solution. (assume T = 25ºC) (3 marks) b. Solve part a) making use of simplifying assumptions. Examine the assumptions. (3 marks) c. The bottle is opened, and the water is poured right into a glass. Assume the the surrounding atmosphere is unpolluted at T = 25ºC. What is the brand-new equilibrium pH? (Hint: You must not have to do any new calculations because that this, yet justify her answer). In regards to the concentration of liquified CO2 varieties (H2CO3 * , HCO3 - , CO3 2- ) describe the changes that take place as the new equilibrium is approached (increase or decrease) (3 marks) d. Bring out this experiment: to water a carbonated beverage (water, coke, 7-UP, beer etc.) right into a glass and also then sprinkle part salt right into the beverage.

Describe and also explain what you have actually observed. Go the enhancement of a little amount of salt influence the equilibrium pH? go it influence the price of technique to equilibrium? What is the function of the salt?
