Acids are sour-tasting compounds that can either donate a proton or accept a lone electron pair. Bases are bitter compounds that accept a proton or donate a lone electron pair.
Lemonade on a hot summer day is the most refreshing! Have you ever wondered where the delicious sour taste comes from? Lemons get their sourness from citric acid, present in almost all citrus fruits. The word acid comes from the Latin word ‘acere,’ meaning ‘sour.’ There are thousands of other ways you interact with acids and bases in your daily life. They are an integral part of our lives. (Interestingly, even the above-mentioned soft drinks contain an acid known as carbonic acid.
Characteristics of Acids

There are countless ways we interact with acids on a day-to-day basis. Examples of acids are:
Just like acids, bases also play a key part in our lives. Examples of bases are:
As you can see, acids and bases aren’t just a random chemistry or biology topic; they have and continue to help improve our living standards across the planet. From the green revolution to better understanding how our body synthesizes protein from amino acids, this topic comes in handy all over.
1. What is an acid, and what is a base?
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
2. What are the differences between acids and bases?
Acids are sour tasting compounds that contain Hydrogen ions (H ) and turn blue litmus papers red. Bases are bitter-tasting compounds that contain hydroxyl ions (OH-) and turn red litmus papers blue.
3. What are five examples of acids and bases?
Acids: Hydrochloric acid, sulphuric acid, nitric acid, lactic acid, hydrobromic acid. Bases: Potassium hydroxide, sodium hydroxide, calcium hydroxide, lithium hydroxide, cesium hydroxide.
4. What are ten examples of bases in everyday life?
5. What are the three types of acids?
The three types of acids are: binary acid, oxyacid, and carboxylic acid Binary acids are hydrogen atoms bonded to nonmetal atoms, written in “H-A” form. Oxyacids have one or more O-H bonds. For example, Sulfuric Acid H₂SO₄. In Carboxylic Acids, only the hydrogen atom in the carboxyl group can be ionized and contribute to acidity.
6. What are the ten examples of acid?
7. What are five acids and five bases?
Five acids: Lemons, oranges, vinegar, urine, sulfuric acid.
Five bases: Soap, toothpaste, bleach, cleaning agents, limewater.
8. What are the uses of bases?
Milk of magnesia (magnesium hydroxide) is used as an antacid or a laxative by helping correct excess acidity in the stomach. Sodium Hydroxide is used in the manufacture of paper, textiles, and detergents. Calcium Hydroxide is used in whitewashing and making bleaching powder.
9. What are the types of acids and bases?
There are 3 types of acids and bases: Arrhenius, Brønsted, and Lewis. Arrhenius acid dissolves in water to release H ions, and bases release OH- ions. Brønsted acids are compounds capable of donating a proton H . Brønsted bases can accept a proton. Lewis acids can accept an electron pair, and Lewis bases can donate one.
10. What is called acid?
An acid is any substance that tastes sour in water, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
11. What do you mean by base?
The positive or non-acid component of a salt, a substance that, combined with an acid, neutralizes the latter and forms a salt; it is also applied to the hydroxides of the positive elements or radicals and to certain organic bodies resembling them in their property of forming salts with acids.
