How can you identify a salt?

Thus the basic salts will be composed of a spectator ion like sodium, Na+, potassium, K+ or something like that and an anion that is the conjugate base of the acid. They can be identified as they are the same compound as the weak acid but they are “missing” a H+.

Which salt has highest pH water?

Among the given salts, Na2CO3 corresponds to the basic salt as it is formed by the neutralisation of NaOH [strong base] and H2CO3 [weak acid]. The highest pH refers to the basic solution containing OH- ions. Therefore, the basic salt releasing OH- ions on hydrolysis will give highest pH in water.

Is na2co3 a basic salt?

Sodium carbonate is a basic salt because it is a salt of .

Is Salt a mixture?

A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.
