Question

The box shows the pH values of the soil in two parts of a garden, $X$ and $Y$.

$X$ $pH=7.0$

$Y$ $pH=5.5$

Lime is used to neutralise the soil in one part of the garden.
To which part of the garden should the lime be added and why?

• A. Part of the garden - $X$, because lime is - acidic
• B. Part of the garden - $X$, because lime is - basic
• C. Part of the garden - $Y$, because lime is - acidic
• D. Part of the garden - $Y$, because lime is - basic

Answer 1

Answer: (D)

Part of the garden - $Y$, because lime is - basic

Soil Y is acidic in nature. Lime is alkaline and it will neutralize the acidity of the soil Y and make it more neutral.
