Question

the concentration of aqueous sodium carbonate can be found by reaction with hydrochloric acid of non concentration using the and methyl orange which item of a equipment are needed​

Answer 1

Explanation:

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

Answer 2

Answer:

You can use the technique of titration to determine the concentration of a sodium carbonate solution using a solution with a known concentration of hydrochloric acid, or vice versa. HCl gradually reduces the alkalinity of the solution until the pH is 7. Because the reaction between sodium carbonate and hydrochloric acid proceeds in two stages, you can use more than one indicator. Phenolphthalein is suitable for the first stage, and methyl orange is best for the second.
