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

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

Select the solution that is likely to be:

(i) Lime water.
(ii) Sulphuric (VI) acid.
(iii) Distilled water.
(iv) Magnesium chloride.



Answer :

Certainly! Let's determine the solutions based on their pH values as provided in the table.

1. Lime water:
- Lime water is basic in nature. It typically has a pH around 9.
- Looking at the table, the solution with a pH of 9 is labeled as F.
- Therefore, the solution likely to be lime water is F.

2. Sulphuric (VI) acid:
- Sulphuric acid is a strong acid and has a very low pH, typically around 1.
- The table shows that the solution with a pH of 1 is labeled as A.
- Therefore, the solution likely to be sulphuric (VI) acid is A.

3. Distilled water:
- Distilled water is neutral and has a pH of 7.
- According to the table, the solution with a pH of 7 is labeled as E.
- Therefore, the solution likely to be distilled water is E.

4. Magnesium chloride:
- Magnesium chloride solution is mildly acidic, typically having a pH around 4.
- From the table, the solution with a pH of 4 is labeled as B.
- Therefore, the solution likely to be magnesium chloride is B.

In summary, the likely solutions are:
(i) Lime water: F
(ii) Sulphuric (VI) acid: A
(iii) Distilled water: E
(iv) Magnesium chloride: B
