moreResolved Question: 1-butanol to 1-bromobutane; why Na-bicarbonate?
We're performing an acid catalyzed Sn2 substitution with 1-butanol and NaBr. My question is: after the reflux, we are to add NaHCO3 to the organic layer and I'm not sure why.
C4H9OH + H2SO4 + NaBr ----> C4H9Br + H2O + NaHSO4.
And I think the addition of NaHCO3 would cause:
NaHCO3 + NaHSO4 -----> CO2 + H2O + Na2SO4
I'm thinking this must be because Na2SO4 has a higher boiling point than NaHCO3 so during distillation a more pure product can be achieved, but I'm not sure if this is right.
So, my question is why add the sodium bicarbonate (NaHCO3) to this before distillation?

So I have this chemical reaction where I am given the reactants (alkaseltzer and water) and I have to find the products. I know that alkaseltzer is sodium bicarbonate (or NaHCO3) and of course water is H20 (by the way, all numbers should be subscripts...Sorry). So I need to know what the reactants are. I'm pretty sure that the sodium replaces one of the hydrogens in the water, which makes sodium hydroxide (NaOH), but then I'm left with a hydrogen and a bicarbonate (HCO3). The only thing I can think of that can come from that is CO2 and H2O, but then what kind of a reaction would that be, because I don't think it's just a double replacement anymore, but I could be wrong.
Anyways, thanks to everyone who can help me out with this one...It's a tough one, or at least for me it is

moreVoting Question: I need chemistry help...!!?
In this laboratory experiment you are to generate sufficient carbon dioxide to inflate a plastic ziploc bag. You first must carry out some calculations to determine the quantity of reagents needed.
The carbon dioxide will be generated by reacting solid sodium bicarbonate (NaHCO3) with a solution of acetic acid (CH3COOH) as follows:
NaHCO3(s) + CH3COOH(aq) ® H2CO3(aq) + CH3COO−(aq) + Na+(aq)
H2CO3(aq) ® H2O(l) + CO2(g)
Question 1:
Of course, this volume is only approximate as the width of the inflated bag is not uniform. To get a better value for the volume, you fill the bag with water, then measure the volume of the water to be 490.2 mL. Now you measure room temperature to be 19 °C and the barometer on the wall gives a reading of 765 torr for the atmospheric pressure. Using the ideal gas law, calculate the number of moles of CO2 that will be required to fill the bag at this temperature and pressure.
Question 2:
Now inspect the reactions above generating CO2 and calculate the molar quantity of NaHCO3 and CH3COOH needed.
Question 3
What mass of NaHCO3 will be needed?
Question 4:
You have a solution of 6.07 M acetic acid. What volume of this solution will be needed?

question:
A small child has eaten baking powder (containing sodium hydrogen carbonate). It shows that the pH of the small stomach (0.5 litter) has risen from 1.5 to 3.5. Calculate how much baking powder the child has eaten. Discuss ev. difficulty in obtaining an accurate estimate
answer by: uncle68
The basic reaction is
NaHCO3 + HCl --> NaCl + H2O + CO2
so one mole of bicarbonate will neutralise one mole of hydrochloric acid. You don't need to worry about the pKa for HCl - it's a (very) strong acid and completely dissociated in solution. The pH measures the change in H+ (or more accurately H3O+) concentration and hence the amount of HCl neutralised.
Since pH = - log([H+])
Initial concentration of HCl = 10^(-1.5) = 3.16 x 10^(-2) M
Final concentration = 10^(-3.5) = 3.16 x 10^(-4) M
Change in concentration = 3.13 x 10^(-2) M
As the child's stomach has a volume of 0.5 litres, this is equivalent to 0.5 x 3.13 x 10^(-2) moles of HCl, and the same amount of NaHCO3.
The molar mass of NaHCO3 is (nearly) 84, so the amount consumed was
0.5 x 3.13 x 10^(-2) x 84 = 1.3 grams.
The main sources of error in the calculation are in estimating the volume of the stomach, and in measuring the initial and final pH values. But in addition, the stomach is a dynamic system which controls the acidity of its contents by generating HCl and NaHCO3, so it would have been taking steps to correct the unexpected consumption of the latter, even in a small child!

A truck carrying barrels of concentrated (18 M) sulfuric acid is involved in an accident, and three
45-gallon barrels fall from the truck and break. A hazardous waste cleanup team arrives and plans
to neutralize the acid spill by treating it with sodium bicarbonate (NaHCO3), which reacts with
H2SO4 according to the equation below. What mass of sodium bicarbonate will be needed to
neutralize the entire spill?
2 NaHCO3(s) + H2SO4(aq) → Na2SO4(aq) + 2 CO2(g) + 2 H2O()

The composition of Alka Seltzer tablet is 325 mg acetylsalicylic acid(ASA), 1000 mg citric acid, and 1916 mg sodium bicarbonate. ASA is monoprotic and has a molar mass of 180 g/mole. Citric acid is triprotic and has a molar mass of 192 g/mol. NaHCO3 is a monofunctional base and has a molar mass of 84 g/mol. When a tablet is dropped in water the components dissolve and react.
a) Write the net ionic equations for the reactions of NaHCO3 with ASA and citric acid.
b) Calculate the # of moles of H+ due to ASA and citric acid.
c) Calculate the # of moles of base due to sodium bicarbonate.
d) Determine whether the acid combination or the NaHCO3 is in excess.
e) Calculate the concentration of the excess component after an Alka Seltzer tablet is dissolved in 50 mL H2O.
