Answer 1

The correct answer is Basic solution

Key Points

As the pH value increases from 7 to 14, it represents a basic solution.
The pH scale ranges from 0 to 14, with 7 being neutral.
A pH value less than 7 indicates an acidic solution, while a pH value greater than 7 indicates a basic solution.
A pH of 7 is considered neutral, which is the pH of pure water.
Common examples of basic solutions include soapy water and bleach.

Additional Information

The pH scale is a logarithmic scale, meaning each whole number on the scale represents a tenfold increase or decrease in hydrogen ion concentration.
The concept of pH was introduced by the Danish chemist Søren Peder Lauritz Sørensen in 1909.
Maintaining the correct pH balance is crucial in various biological and chemical processes, including human blood, which must stay within a narrow pH range of 7.35 to 7.45.
Indicators, such as litmus paper and pH meters, are commonly used to measure the pH value of a solution.
Buffer solutions are used to maintain a stable pH in various applications, including biochemical assays and fermentation processes.
