Sodium hydrogencarbonate is used as baking powder for making cakes. When the cake mixture is baked the sodium hydrogencarbonate decomposes. The equation for the reaction is: 2 NaHCO3(s) --Heat--> Na2CO3(s) + H2O(g) + CO2(g) 1 (b) (i) The cake mixture rises when baked. Use the equation to suggest why. (1 mark) 1 (b) (ii) The same reaction can be reversed to produce sodium hydrogencarbonate from sodium carbonate. Na2CO3 + H2O + CO2 ---> 2 NaHCO3 Do the reactants need to be heated? Give a reason for your answer. (1 mark)

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
