Thank you @jennypearl7921! Yes, it is! Why we didn't analyse it here is because you cannot use an aqueous solution of the commonly used reagents to analyse it. However, you can use a FLAME TEST to analyse sodium. Take a little portion of the salt using the flat end of your spatula and heat it directly in a Bunsen flame. Bright or golden yellow flashes indicate the presence of sodium ions
It's easy. For your HCl, dissolve 170 cm3 of the stock acid in 1 dm3 of water. DO NOT ADD water to the conc. (stock) acid. That will give you a 2 M HCl solution. For the BaCl2, measure the mass of between 1 - 2 mol of the salt and dissolve in water 1 dm3 of water.
Good morning Science chef, thank u for all u do. My question: what of in a situation where lime water was not asked in the question, would there still be a need to report that in the observation Or should we stick to what the question demands. Thank u sir
Most times, they would not ask you to use lime water in the question; but they would expect you to use it as a confirmatory test for carbon (IV) oxide....because it is one of the reagents you are expected to have in the laboratory.
Thanks teacher
You are welcome student!🙏🤜🤛
Yo! It's the Science Chef again!🙌🙌🙌
😂😂😂🤜🤛
Thanks Sr
You are welcome Peace!🙏
Thank u very much
You are welcome! We are glad that you like it!
Well done sir 👏👏👏
Thank you for watching!🙏
More clear pracs
Thanks for watching!
well done sir. You always do wonderfully well. Is sodium ion a spectator ion? It wasn't analyzed here sir

@@TheScienceChefAcademy Good one. Thank you sir.
You are welcome!🙏
Sir, whats the mass conc of ur HCl and BaCl reagents
You can use a 2 M HCl, prepared by dissolving 170 cm3 of the stock acid in 1 dm3. For the BaCl2, you can dissolve 2 mol in 1 dm3
This is great Sir
Thank you so much ❤
You are welcome @oladunnijosephakin!
Thanks alot
You are welcome!🙏
Thank you sir✊🏽
You are welcome @opinions7993
Thanks sir...please can you explain how to prepare reagents for qualitative analysis pls

Please what’s the name of the salt?
It's sodium trioxocarbonate (IV)
I request to prepare lesson about solubility
Alright, we'll see what we can do!
Great one
What of the cation in d salt
The cation is not a regular cation normally tested in qualitative analysis using aqueous reagent, except by flame test. The cation is Na+
