Acid vs Base: Difference and Comparison

Acids and bases are seen in our daily life. The foods we eat and the things we use have either acid or base in them. Even some acids are found in our human body, which will help us in the digestion process.

These are studied in depth in chemistry as they deal with chemical components.

A basic of them will be explained at the school level so that we can understand the difference between strong acids and strong bases. 

Key Takeaways

  1. Acids are substances that donate hydrogen ions (H+) in a solution, while bases accept hydrogen ions.
  2. Acids taste sour and have a pH of less than 7, whereas bases taste bitter and have a pH greater than 7.
  3. Acids turn blue litmus paper red, while bases turn red litmus paper blue.

Acid vs Base

Acids are chemical compounds that can be corrosive to metals, such as hydrochloric acid, sulfuric acid, and acetic acid. A base is a chemical compound that accepts hydrogen ions in a chemical reaction and has a bitter taste and slippery feel. Examples include NaOH, KOH, and ammonia.

Acid vs Base

Acids are found in food and the human body. The acids that are produced in the human body are good for health.

There are two important types of acids called organic acids, and the other one is called inorganic acids. Organic acids will have a carbon content in them.

Inorganic acids will not have a carbon content in them.

If you feel acid excess in your body, then there are some steps available to remove them. 

A base is a chemical compound that will absorb hydrogen ions. The baking soda that we use in our food will come under the base.

We can determine whether the foods or daily things we use are basic or not by determining their PH value. Bases have some properties.

They always have a bitter taste. They also help in conducting electricity.

There are some bases which are really good conductors of electricity.

What is Acid?

Acid is a chemical compound. When you dissolve acid in the water, it will give a sour taste. Also, acids will burn some substances that come in contact with them. Acids will donate H+ ions.

Acids will be formed when hydrogen ions are released, and the solutions will become acidic. These ions will determine whether they are acid or base.

When you dissolve them in water, the balance between ions will be shifted. Acids are also available in the human body for digestion.

Many acids are available inside the human body. There is an acid called battery acid, which is very strong as it will give the energy needed for the body.

Acids in the body will help in digestion and energy production. Acids are also found in human genes.

Acids will be found inside the cells and the digestive system. Acids are also found in natural foods.

These acids in the food will also help digestion. Many strong acids are available, which will affect our human body when we come in contact.

There are also three types of acids available. They are binary acid, oxyacid, and carboxylic acid.

These acids will be explained well in chemical form.

There are amino acids in the body that will help the proteins in the body. Acids are also used in car batteries. Acids also cause side effects in the human body, such as blood pressure and insomnia. 


What is Base?

The base is a compound that will change the colour of indicators. A base will have protons, and, in some cases, it will accept electrons to form a bond.

They are the exact opposite of acids. Sometimes the reaction between an acid and base will lead to a neutralization reaction.

There are many strong bases available in chemistry with their chemical name itself. We use haircare and body care products daily will come under the base.

Because if the shampoo has a PH value greater than 7, then it will affect the condition of the hair. Once the base level exceeds, then people will start to feel severe hair problems in their hair.

A soap will have a combination of base and acid. But the base will be higher in soap, and the acid will be less. If we use base completely in soap, then it will not be good for our skin.

Maintaining a good PH level is very important. The soap that we use for cleaning should also have the correct combination of base and acid.

If the combination is incorrect or something is added in excess, the clothes will lose their quality faster. We can see the common examples of the base in our household.

The majority of the products that we use in-house will come under the base. A good nucleophile is called a good base.

If the blood in our body is greater than 7 and maintains some range, then it will come under the base.

The doctor will evaluate it by seeing the carbon dioxide and bicarbonate in the blood.

Main Differences Between Acid and Base

  1. Acids are chemical compounds that will provide hydrogen ions when dissolved in water. On the other hand, the base is a chemical compound that will absorb the hydrogen ions.
  2. The strength of the acid is based on hydronium ions. On the other hand, the strength of the ions is based on hydroxide ions.
  3. The PH value in acid is less than 7. On the other hand, the PH value in the base is greater than 7.
  4. Acid can be used as a preservative in food. On the other hand, the base is used in making shampoos and soaps.
  5. When acid is placed in litmus paper, it turns blue into red. On the other hand, when the base is placed on litmus paper, it will turn red into blue colour.
