(b) The table below shows the pH of some solutions.

\begin{tabular}{|c|c|}
\hline Solution & pH \\
\hline A & 1 \\
\hline B & 4 \\
\hline C & 5 \\
\hline D & 3 \\
\hline E & 7 \\
\hline F & 9 \\
\hline G & 12 \\

\end{tabular}

Select the solution that is likely to be:
(i) Lime water.
(ii) Sulphuric (VI) acid.
(iii) Distilled water.
(iv) Magnesium chloride.

Certainly! Let's go through the given pH values of the solutions step by step and determine which solution corresponds to each substance:

1. Lime water:
- Lime water is known to be a basic solution and typically has a high pH value around 12.
- From the table, the solution with a pH value of 12 is G.

So, the solution corresponding to lime water is G.

2. Sulphuric (VI) acid:
- Sulphuric acid is a very strong acid, and strong acids have very low pH values. Typically, the pH of sulfuric acid is around 1.
- From the table, the solution with a pH value of 1 is A.

So, the solution corresponding to sulphuric (VI) acid is A.

3. Distilled water:
- Distilled water is neutral, meaning it has a pH of 7.
- From the table, the solution with a pH value of 7 is E.

So, the solution corresponding to distilled water is E.

4. Magnesium chloride:
- Magnesium chloride forms a slightly acidic solution, with a pH typically around 5-6.
- From the table, the solution with a pH value of 5 is C.

So, the solution corresponding to magnesium chloride is C.

Thus, the solutions corresponding to each of the substances are:
1. Lime water: G
2. Sulphuric (VI) acid: A
3. Distilled water: E
4. Magnesium chloride: C
