FAQs on Summary: Acids, Bases and Salts Video Lecture - Basic Science for JSS 2

1. What are some common examples of acids, bases, and salts?
Ans. Some common examples of acids include vinegar, lemon juice, and battery acid. Examples of bases include soap, baking soda, and ammonia. Examples of salts include table salt (sodium chloride), Epsom salt (magnesium sulfate), and rock salt (halite).
2. How do acids and bases differ in terms of their pH levels?
Ans. Acids have pH levels below 7, with lower pH values indicating stronger acidity. Bases have pH levels above 7, with higher pH values indicating stronger basicity. A pH of 7 is considered neutral.
3. How do acids, bases, and salts react with each other?
Ans. Acids react with bases to form water and a salt. This reaction is known as neutralization. Salts are formed when acids and bases combine, with the properties of the resulting salt depending on the specific acid and base used.
4. What are some common uses of acids, bases, and salts in everyday life?
Ans. Acids are used in cleaning products, food preservation, and industrial processes. Bases are found in household cleaning products, personal care items, and agriculture. Salts are used for seasoning food, melting ice on roads, and in various industrial applications.
5. How can the strength of an acid or base be determined?
Ans. The strength of an acid or base can be determined by its pH level. A lower pH value indicates a stronger acid, while a higher pH value indicates a stronger base. Additionally, the concentration of the acid or base can also affect its strength.
