What are the steps to prepare a salt starting with an alkali(titration)?
Autor: Anov FernandoRespuesta:
1) Put alkali into a flask using a pipette, add two drops of phenolphthalein. 2) Add the acid from the burette just a little at a time, swirl the flask carefully to help the acid and alkali mix. 3)Once the indicator turns colorless all the alkali has been used up so no more acid should be added. 4) Use the burette to find how much acid was added to neutralize the alkali. 5) Now repeat the without the indicator(it would be an impurity) , use the same volume of alkali then add the right volume of acid required to neutralize the alkali. 6) Heat the solution from the flask to evaporate the water, crystals of the salt will be left behind
