Question

Sulphuric acid, such as found in a car battery, is a strong

acid with a pH value near to the value
a) 7
b) 9
c) 14
d) 0
e) 8

Answer 1

Sulphuric acid in a car battery is a strong acid with a pH value near 0, which is highly acidic compared to a neutral pH of 7 or a basic pH of 14.

Step-by-step explanation:

Sulphuric Acid and pH Value

Sulphuric acid, which is utilized in car batteries, is a strong acid with a high level of chemical activity. It ionizes into hydrogen ions and sulfate ions, dramatically influencing the pH of a solution. Based on the pH scale, where lower values indicate higher acidity, sulphuric acid found in car batteries has a pH value near 0. In fact, the pH of battery acid is noted to be approximately 0.3, making it one of the more acidic solutions on the scale.

In comparison, a pH of 7 is neutral (like pure water), while a pH of 14 is highly basic (like liquid drain cleaner). Therefore, amongst the given options, the most accurate answer to the pH level of sulphuric acid in a car battery is d) 0, reflecting its strong acidic nature.
