Important Points

  • pH scale was discovered by Soren Sorensen.
  • The range of pH scale 0 to 14.
    • If pH < 7 then solution is acidic.
    • If pH > 7 then solution is basic.
    • If pH = 7 then solution is neutral.

Additional Information

• pH means the potential of Hydrogen.
• The strength of acids and bases depends on the number of H⁺ ions and OH^- ions produced, respectively.
• The human body works within the pH range of 7.0 to 7.8.
• When the pH of rainwater is less than 5.6, it is called acid rain.
• Tooth decay starts when the pH of the mouth is lower than 5.5.

Concept:

An array is a data structure that contains a group of elements. These elements are all of the same data type, such as an integer.

To access element from an array subscript(index) and array name is required

Explanation:

Array name: A

To access 3^rd element in an array A[2] or 2[A] is used.  Therefore Both A[2] and 2[A] represent the value 3

Important point:

A[0] represent the value 1^st element

Preparing the family tree using the following symbols,

Given:

Mahendra is the son of Naman, who is the brother of Reema’s mother.

1) Mahendra is the son of Naman.

2) Naman is the brother of Reema’s mother.

We can draw following Family Tree from the information given above:

Hence, the Mahendra is the "Cousin" of Reema.
