O Level Chemistry – Physical & Chemical Properties of ACIDs

Today, we are going to look into the properties of Acids. In Chemistry learning, whenever we talk about properties, we will always look into both the Physical & Chemical Properties of the substances.

PHYSICAL PROPERTIES OF ACIDS:
1. Acids have a SOUR taste
2. All acids are SOLUBLE in water
3. Acids solutions turn BLUE litmus paper RED
4. Acid solutions have a pH values < 7
5. Most acid solutions are CORROSIVE
6. All dilute acids CONDUCT ELECTRICITY due to the presence MOBILE IONS in solution

So far so good on the Physical Properties of Acids, now let’s look on the Chemical Properties then..

CHEMICAL PROPERTIES OF ACIDS:
1. React with reactive metals (above H in Reactivity Series) to form Salt & Hydrogen Gas
2. React with Metal Carbonates to form Salt, Carbon Dioxide & Water
3. React with Bases/Alkali to form Salt & Water (Neutralistion Reaction)

Is this GOOD or GOOD??? Let us know see how much you have learnt, by checking out some exam-based questions.

Quick Check 1:
Name the products of the following reactions:
(i) zinc + hydrochloric acid
(ii) iron + sulphuric acid

Quick Check 2:
Which property does hydrochloric acid have?
A. It liberates ammonia from ammonium salts
B. It reacts with any base to give a salt
C. It reacts with any metal to give a hydrogen
D. It turns red litmus paper blue

Quick Check 3:
Which substance is not used to prepare zinc chloride by reaction with hydrochloric acid?
A. zinc carbonate
B. zinc hydroxide
C. zinc nitrate
D. zinc oxide

Many know me as the Ten Year Series book author for JC A-Level H2 Chemistry and O-Level Pure Chemistry. My 19+ years of coaching experience (since 1999) with more than 1500 students from 180+ JCs and Secondary Schools has allowed me to understand the true reasons why students are not able to perform well in Chemistry. Most importantly, my strength lies in using everyday analogies (even grandmothers can understand!) to simplify abstract concepts. Also, my teaching methodology has been designed to be fun, enjoyable and effective for my students.
