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?

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
