Describe how you can prepare crystals of sodium nitrate starting with 200cm of 2M sodium hydroxide
You don't mean 200 cm; you mean 200 cm^3 or 200 cc. cm is a length. cc is a volume.

Oh, preparing crystals of sodium nitrate starting with 200 cm of 2M sodium hydroxide? Well, that's quite a process! Grab your lab coat and let's dive in!
Step 1: Pour your 200 cm of 2M sodium hydroxide solution into a beaker. Remember, safety first! Keep those goggles on!
Step 2: Now, it's time to add nitric acid to the beaker. Gently pour the acid into the beaker while stirring. Be careful not to add too much, or it might turn into a "nitric acid dance party" – and trust me, nobody wants that!
Step 3: Heat the mixture gently while stirring until all the sodium hydroxide and nitric acid react. Just like a DJ at a party, keep the temperature at a moderate level – no need to turn up the heat too much!
Step 4: Once the reaction is complete, allow the mixture to cool down. It's like cooling down after rocking out at a concert – take it easy and let the solution settle.
Step 5: Now, crystals should start forming in the beaker. These little gems are your sodium nitrate crystals! If you're lucky, they might even sparkle like diamonds (in a chemist's dreams, of course!).
Step 6: Carefully collect the crystals using a filter paper or suction filtration setup. Remember, these crystals are precious, so handle them gently, like you would handle high-priced jewelry!
Step 7: Lastly, rinse the crystals with some distilled water to purify them. This step is like giving your crystals a refreshing shower, making them all shiny and clean!
And voila! You now have your very own crystals of sodium nitrate. Enjoy the fruits of your labor, but remember, no sneaking them into your jewelry box!
To prepare crystals of sodium nitrate, starting with 200 cm³ of 2M sodium hydroxide, you will need to go through several steps. Here's a step-by-step guide on how to do it:
1. Calculate the required amount of sodium nitrate: As sodium hydroxide (NaOH) and sodium nitrate (NaNO₃) have a 1:1 stoichiometric ratio, the amount of sodium nitrate required will be the same as the amount of sodium hydroxide. In this case, since you have 200 cm³ of 2M sodium hydroxide, the amount of sodium nitrate required will be 200 cm³ as well.
2. Prepare the sodium nitrate solution: Measure out 200 cm³ of distilled water and add it to a clean beaker.
3. Add the sodium hydroxide: Slowly add the 200 cm³ of 2M sodium hydroxide solution into the beaker containing distilled water while stirring continuously. This step is important to ensure thorough mixing.
4. Evaporate the solution: Transfer the solution from the beaker to an evaporating dish or a heat-resistant container. Place the dish on a hot plate or a water bath and start heating gently. The heat will allow the solvent (water) to evaporate while leaving behind the sodium nitrate crystals. Stir the solution occasionally to promote uniform crystal formation.
5. Continue heating and stirring: Maintain a gentle heat, ensuring that the solution does not boil vigorously, as this may cause splashing or crystal disruption. Continue stirring until the remaining liquid has evaporated, leaving behind only the solid sodium nitrate crystals in the evaporating dish.
6. Collect and store the crystals: Once all the liquid has evaporated, turn off the heat source and allow the dish to cool to room temperature. The crystals of sodium nitrate will have formed during the cooling process. Collect the crystals using a spatula or scoop, and transfer them to a clean, dry container for storage.
Finally, remember to label the container with the name and date of preparation to maintain accurate records.
It's important to note that when handling chemicals, safety precautions must be followed. Wear appropriate personal protective equipment, such as gloves and goggles, and work in a well-ventilated area to avoid inhaling any fumes or dust. Additionally, disposal of chemicals should be done according to your local regulations.
