Data Given:
[H⁺] = 3.16 × 10⁻⁷ M
To Find:
pH = ?
Solution:
As we know that,
pH = -log [H⁺]
Putting values,
pH = -log (3.16 × 10⁻⁷)
pH = 6.50
Kind of Solution:
As we know, when pH of a solution is equal to 7, it is Neutral. When less than 7, its Acidic and when greater than 7, it is Basic. As this solution has pH 6.50, which is less than 7, so it is slightly Acidic in Nature.
<u>Answer: </u>The correct answer is Silver.
<u>Explanation:</u>
Specific heat of fusion is defined as the amount of heat which is required to raise the temperature of 1 gram of a substance to 1°C. It is generally expressed in kJ/mol
We are required to find the substance which require more heat. For that we need to know the specific heat of all the substances.
The substance which have the highest specific heat, will require more heat.
The specific heat of the given substances are:
Silver = 11.3 kJ/mol
Sulfur = 1.7175 kJ/mol
Water = 5.98 kJ/mol
Lead = 4.799 kJ/mol
The specific heat of silver is the highest and hence, will require more heat.
Hence, the correct answer is silver.
