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
