how can one get h2so4 from sodium bi carbonate?
i think instead of prepare it should be neutralize.
mL acid x N acid = milliequivalents acid = 45.6 mL x 0.235 = m.e. acid
1 m.e. of anything = 1 m.e. of anything else; therefore, m.e. acid = m.e. Na2CO3.
m.e. acid = m.e. Na2CO3.
m.e. Na2CO3 x milliequivalent weight Na2CO3 = grams Na2CO3
m.e. Na2CO3 x 0.053 = grams Na2CO3.
45.6mL x 0.235N x 0.053g/m.e. =0.56795 g of 100% Na2CO3. Since it is only 85%, then
0.56795/0.85 = 0.66
