Question

2) You work in a lab where somebody has spilled a 2.5 L bottle of 6.0 M hydrochloric acid on the floor. The spill is confined to a small area. Your supervisor tells you to neutralize the spill with baking soda, but she doesn't tell you how much to use. Then you realize the last of the baking soda has been used to clean a previous spill, and you need to buy some from the store. How many boxes of baking soda will you need to completely neutralize the hydrochloric acid? Baking soda containers come in different sizes, and it does not matter which size you buy. To answer the question, state the size of number of containers you choose to buy. You will likely have to do some online research to answer this question.

Explanation / Answer

The hydrochloric acid can also be said as HCl in the formula term. it the one of the strong acid which contain the anion as hydrogen that is H and the cation as the chlorine that is Cl. thus by the mutually combinations they forms the hydochloric acid. now when it need to neutralized this means that we need to equate the amount of the cation and the anion with the same emperical amount. in this neutralization the pH will be 7 and thus we need to treat with the base.

as we know that when we treat the base with the acid or vice versa. if the both the reactant have the equal amount and the molecular weight then they have the same emperical weight also and correspondigly have the state of nutral equallibrium with the anion and the cation exchange rate in the reactions.

as we know that when an acid is treated with the base we get the salt and the water. this reaction is termed as the nutralization reaction. now we take an example to understand this.

Hcl + NaOH-->NaCl + H2O. where we have the NaCl as the salt and the other is the water.

now take the case of problem where we need to neutralize the Hcl with the help of baking soda as baking soda is also a base so we can use it. but the question arises here is that what amount or what will be the quantity of baking soda which we need to use in order to attain the neutralization reaction. then it can be determine by the simple method of the emperical relation. so first of all we need to know the amount of the molecular weight of the spilt acid. say HCL =37 gm/ mole

thus we need to put the same amount of the baking soda that is we required 37 gm/mole weight of baking soda to get the neutralization in this case.
