How to make 1 molar sodium bicarbonate?

Attention all wannabe chemists! Have you ever wondered how to make 1 molar sodium bicarbonate? Well, look no further because we’ve got the ultimate guide for you. In this article, we’ll take you through all the steps needed to create your own magical potion.

But before we get started, let’s get one thing out of the way: if you’re easily intimidated by sciencey stuff and big words that your middle school teacher would use in a spelling bee, don’t worry – we promise to keep it light and fun! So put on your gloves and goggles (seriously tho) and let’s jump right into it!

What is Sodium Bicarbonate?

First things first – what exactly is sodium bicarbonate? For those who aren’t already familiar with this stuff or need a refresher, sodium bicarbonate, also known as baking soda (for those lost souls who have never baked cookies), is a white crystalline powder that is commonly used as a leavening agent in baking. It has many other uses too depending on its ‘pH’ nature.

pH nature: pH refers to potential of hydrogen ions in solution(predictably hydrogen close to metals). The pH scale measures from 0-14 with lower numbers being more acidic(higher concentration] while higher pH values are considered basic [or alkalinity].

Now, without further ado…

Ingredients

To make our magic potion, here’s what you’ll need:
– Sodium Hydroxide (NaOH)
– Carbon Dioxide Gas
– Water (a.k.a H2O)

You may be asking yourself now “wait… where’s baking soda?” Please bear with us for just a moment – all will become clear soon enough.

Why not using Baking Soda Directly?

The reason why plain old baking soda isn’t listed as an ingredient is because, believe it or not, sodium bicarbonate (baking soda) can’t actually be prepared by directly mixing the elements that make it up (that’s sodium, hydrogen carbonate and carbon dioxide).

“What!? How come?”
well youngling.. “let me break it down for ya”
The basic ammonium equilibrium reaction process dictate ‘Bas+HCO3–> NaHCO3′ will form Sodium bi-carbonate. However since we cannot keep gases like CO2 inside compound crystals of NaOH which easily react with water to dissociated ions into solution making precipitation impossible

Step-by-Step Guide

Now let’s get to the fun part – making some magic happen with our ingredients! Here are the steps:
1. Fill a round-bottom flask halfway with water (make sure you use one that can withstand heat and pressure)…
2. …And carefully mix in solid Sodium Hydroxide flakes/pellets(NaOH). You’ll notice a rush of heat being generated from exothermic reaction; don’t panic – this totally normal.
– What are exothermic reactions mean again? Exo means outwards while thermic refers to temperature/heat energy…so in essence an exothermic chemical reaction generates/release heat outside.

Tips When Adding Sodium Hydroxide

When adding your hydroxides.NaOH stick to small adds so as not generate too much rapid-release excess heat due nature(the infamous exponential function)of acid-base-neutralization using concentrated chemicals_. Also actively stirring helps avoid any hot-spots/temp variations on ur container.

  1. Once everything has settled give enough time enough for more thorough mixing/dissolving.Cooling down over ice/water bath is often recommended but remember caution when handling dry ice near flesh/wet surface.
  2. Gently bubble Carbon Dioxide gas through the mixture; note how things might start getting a little fizzy if you’re multi-tasking and trying to listen the top 100-chart music simultaneously. That is normal, no need to call for a fire extinguisher or emergency services.
  3. Just make sure you are using pure Carbon Dioxide gas, as other types of gas may lead to unwanted chemical reactions
  4. Continue bubbling CO2 through the mixture until saturation point is reached typically indicated by slower reaction rate(quite similar to soda refreshing). This means that there’s no longer any change in mass when additional carbon dioxide is added.

How 1 Molar Sodium Bicarbonate Is Made?

Finally, we’ve arrived at our destination! The addition of Carbon Dioxide(CO2) pushes the below ammonium equation into product balance realm
Bas+HCO3 ⇌ NaHCO3
where Ba stands for conjugate base
And voila – You’ve just made your very own sodium bicarbonate (NaHCO3)! Pat yourself on back(yes do that literally), dance with joy(i said literally not dabble)and repeatedly say “I did it” (preferably around others who can hear ya).

Here’s how to calculate its molarity:

Firstly let’s define what molarity actually means:
Molarity:= moles of solute/volume(in litres)_of solution
Given an example; If you add twenty-fivegrams(25g)of NaHC03 solid substance into distilled water(volume =five hundred millilitres[500ml] – this will dissolve completely due initial exothermic release from hydroxide.Choosing water instead of another solution somewhat avoids containing additional ions which could interfere or disrupt our final recipe). Once dissolved we’ll obtain one-half litre [0.50L]volume(Since mols=mass/mr…)
Mr(molecular weight)=40g/mol(fyi).
So now on to our molar method:
1. Calculate Molecular Weight (molecular weight of sodium bicarbonate or NaHCO3 = 84g/mol)
2. Calculate the number or grams of NaHCO3, given that we want a 1 M solution and we are dissolving in 0.50 L volume of H20:

  • Number Grams (g)= moles x molecular weight
  • Step-by-step calculation is:

    moles: 1 mol/L=1M

    Volume: 0.5L

    Therefore;

    Moles required = .5mol

    Mass(grams)                    =       `40 .5mol(g/mol)`
                                            `=`   `20 g.`             This means you need to dissolve twenty grams [20gm]of your newly created NaHCO3 into half litre[500 ml] for an exact one molar mixture.
    

Proper Storage Methods For Sodium Bicarbonate

Just like any other chemical reagent purchased,to maximize shelf-life, product concentration/stoichiometry should be wary maintained.Ther perils of having too concentrated mixtures easily lead to dangerous/reactionary issues.Consult with your local scientific store for safe keeping/presenting recommendations

That’s it! Now you know how to create your own sitting-at- home/easy-to-follow recipe for sodium bicarbonate.You can apply this skills on larger batches(for the mean time pls avoid publicizing). With this knowledge under ur creditial belt(even if not chemically related),who knows what culinary masterpieces/smooth-textured pancake/waffles can come from these instructions?

P.s Issa joke – don’t actually eat chemicals plz(you’ve been warned!)
