Baking soda (sodium bicarbonate) is often used to neutralize spills of acids on the benchtop of the laboratory. What mass of sodium bicarbonate would be needed to neutralize a spill consisting of 25.2 mL of 6.01 M hydrochloric acid solution?

Answer : The mass of needed is, 12.7 grams.

Explanation :

First we have to calculate the moles of HCl.

Now we have to calculate the moles of

The balanced neutralization reaction will be:

From the balanced chemical reaction we conclude that,

As, 1 mole of HCl neutralizes by 1 mole of

So, 0.151 mole of HCl neutralizes by 0.151 mole of

Now we have to calculate the mass of

Molar mass of = 84 g/mole

Therefore, the mass of needed is, 12.7 grams.
