I am doing a lab on Creating An Effective Airbag. We need to find out how much of the base is needed, which is NaHCO3,if we have 2.25 M of HCl, which is the acid. How much of the sample do we need? and how do we find out how much we need?

1 answer

HCl + NaHCO3 ==> NaCl + H2O + CO2
You don't have enough information to answer the question. You have M HCl and that's all. You must have the volume of HCl if you are to calculate the grams NaHCO3. I might point out that this would not be a very good airbag as it would splatter HCl all over the inside of the vehicle AS WELL AS THE OCCUPANTS. 2.25M HCl could cause extensive damage especially to the eyes.
