Making a salt from an alkali + acid

GCSE Chemistry - how to make a salt from an alkali (a soluble base). You have to exactly neutralise the alkali because both the acid and the alkali are soluble, so it is not possible to remove the excess of one of them by filtration.

[@spring3459]

When this was made 6 years ago but you have to learn it for school :(

Oh geez I wish my chem teacher had a delivery like you . I would have been a chemist for sure but he destroyed it with his lack of respect for teaching and enthusiasm . Oh well I suppose I am lucky at 46 I have google and still thirst for knowledge ! Thanks for existing and your teaching style 🙏

1-Fill a 25 cm3 pipette with NaOH 2-Pour the 25 cm3 of NaOH in a conical flask 3-Add 5 drops of Phenolphthalein to the flask (the colour will change to pink) 4-Carefully add HCL from the burette to the flask till the solution becomes colourless 5-Observe the exact volume of HCL needed for the reaction to neutralise 6-Repeat the experiment again with the same volume of acid and base without adding an indicator 7-Heat the salt solution till the point of crystallisation 8-Cool it, Crystals of the salt is formed

What is the concentration for both chemicals plz

[@richardhiggins6471]

The HCl was 0.1mol/dm3. I added 11.8cm3 of this to neutralise 25cm3 of NaOH, so in an exam question you might well be asked to work out the concentration of NaOH yourself. Have a go!

[@avramesther218]

Thank you, Dr.

[@zerotwo3747]

Can we drink this ?

[@richardhiggins6471]

NO! Never drink anything in a science lab. Even if all the apparatus was 100% clean, and you had done the experiment perfectly to get a neutral solution (which is unlikely), it is still harmful. A relatively concentrated solution of salt is harmful and would make you sick.

[@zerotwo3747]

Richard Higgins thank you so much sir ☺️☺️😊

thank you so so usefull covered evrything!!!

[@alphabrainy2676]

can I eat that? u know like sprinkle it on food?

[@richardhiggins6471]

In theory, if the experiment was done perfectly, you would just have pure salt (sodium chloride) at the end of the experiment so you could sprinkle it on your food, but there's no way you would literally do that as there might be impurities in the chemicals, dirt on the equipment etc.

[@praveenpraja7694]

is it necessary to add pH solution???

[@richardhiggins6471]

You add phenolphthalein indicator (not pH solution) first time you do it to make sure that the alkali is exactly neutralised. Then you repeat with exactly the same volume of acid and alkali.

[@aaronlad7697]

@@richardhiggins6471 why does he mention getting rid of the indicator when repeating the experiment as this time no indicator is used, and so only the water needs to be removed to get pure crystals?

[@chemistrywithdrh6514]

@@aaronlad7697 Yes, you don't need indicator second time because you know how much acid is required to neutralise the alkali. So second time you just have a solution of sodium chloride. Evaporate the water and you are left with pure sodium chloride.

Afterwards, filter the mixture and wash with cold distilled water and dry in an oven until it becomes a constant mass. Then, leave to cool in a desiccator.

These steps wouldn't be necessary - not for a GCSE experiment anyway.
