Transcript – Acids Bases Salts

For the topic of acids bases salts, you need to know that there are 2 types of acids. They are: are strong and weak acids. The 3 acids you need to know are dilute hydrochloric acid (HCl), dilute sulfuric acid (H2SO4) and nitric acid (HNO3).

These three strong acids dissociate completely in water. Once they dissociate completely in water, they produce a high concentration of ions versus weak acids like citric acid, lactic acid and ethanoic acid that only partially dissociates in water.
Because they only partially dissociate in water, they produce a low concentration of H+ ions.

The first reaction is Acid and Metals react and produce a Salt and Hydrogen gas.

Second equation is Acid + Metal Carbonates and produces Salt + Carbon Dioxide + Water. Carbon dioxide is produced due to the presence of a carbonate.

The last equation is Acid + Base gives you Salt and Water.

And now, we’ll move on to the bases part of acids bases salts. Many students are confused about bases. Are a base and alkali the same? A base and alkali are not the same. Bases are oxides and hydroxides.

There are both soluble and insoluble oxides and soluble and insoluble hydroxides. Soluble hydroxides are alkalis. An alkali is a base, but a base is not always an alkali.

For alkali reactions, there is only one alkali reaction you need to know. Alkali + Ammonium salt produces Salt, Ammonia gas and water. When alkali reacts with an ammonium salt, it produces the salt, ammonia gas and water.
