B) An open beaker holds 1500 g of water saturated with carbon dioxide at 20°C. The beaker is heated to 60°C.
i) What mass of carbon dioxide would be expected to be lost from the beaker? (2 marks)
ii) The actual loss in mass of the beaker and contents is greater than the value calculated
in part i) Suggest why. (1 mark)

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
