Adding Some Bubbles To The Kicked Bestest Sugared Drink

Now, we are going to add in Sodium bicarbonate (Baking soda), Na₂(HCO₃)₁ (solid form), to the drink. However, Sodium bicarbonate reacts with the Citric acid to produce an acid and a salt in a double replacement reaction. Write the balance equation below:



Remember, the Citric acid (H₃C₆H₅O₇) is called triprotic acid since 3 of H are used as H⁺ and the other 5 do not).
But the acid does not stay together but instead form a gas and water, so the above equation becomes:

This is the third type of double replacement reactions that occur, "gas product".

To determine how much Sodium bicarbonate your "existing citric acid/sugared drink" will need to remove all the citric acid, you need to do a stoichiometry calculation.
Once you have the mass of sodium bicarbonate to react with all the citric acid (this is called Stoichiometric amount so there is no limiting reactant or both reactants are), you will need to determine the amount of gas you are going to generate.

Here is the link for Gas Generation calculations, Gas Generation (under water and not) and Molar Volume of Gas Law

We are assuming that the gas is at room temperature (°C) so check/write down room temperature each day. Of course, the above reaction will remove the "kick" or "sour" taste to your drink. But what if you want to keep some of the "sour" taste, then you are going to have to recalculate the amount of sodium bicarbonate you use or add in more citric acid (your choice.

You have 3 tries at getting the right "recipe of citric acid, sodium bicarbonate and sugared drink".
Each try will require you to calculate the sodium bicarbonate used and gas generated (in mL). Other calculations may be needed if you change either sugared reactant and/or citric acid.

Here is a link to Limiting reactant problems just in case you need to do that calculations, as part of your recipe "making" step, (Limiting Reactant Problems).
