One JTU is equivalent to turbidity produced bya)1mg of fine silica dis...
Explanation:
The turbidity of a solution is a measure of the cloudiness or haziness of the solution, caused by the presence of suspended particles. It is commonly measured using a turbidimeter, and the unit of turbidity is called the Jackson Turbidity Unit (JTU).
The question asks for the equivalent turbidity produced by different amounts of fine silica dissolved in distilled water. Let's analyze each option:
a) 1mg of fine silica dissolved in 1L of distilled water:
This option states that 1mg of fine silica is dissolved in 1L of distilled water. Since turbidity is a measure of suspended particles, it is expected that the more particles present, the higher the turbidity. Therefore, the turbidity produced by 1mg of fine silica dissolved in 1L of distilled water would be minimal compared to other options. This option is incorrect.
b) 1g of fine silica dissolved in 1L of distilled water:
This option states that 1g of fine silica is dissolved in 1L of distilled water. Since the amount of silica particles is higher compared to option a), the turbidity produced by this solution would be higher. However, it is important to note that JTU is a standardized unit, and it is unlikely that 1g of fine silica dissolved in 1L of distilled water would produce the exact turbidity defined as 1 JTU. This option is incorrect.
c) 1g of fine silica dissolved in 1ml of distilled water:
This option states that 1g of fine silica is dissolved in 1ml of distilled water. The amount of silica particles is significantly higher compared to both options a) and b). Therefore, it is likely that this solution would have a higher turbidity. However, the volume of the solution is only 1ml, which is significantly smaller than the standard measurement of 1L for turbidity. This option is incorrect.
d) 1mg of fine silica dissolved in 1ml of distilled water:
This option states that 1mg of fine silica is dissolved in 1ml of distilled water. Although the amount of silica particles is the same as option a), the volume of the solution is significantly smaller. This means that the concentration of silica particles in this solution would be higher, resulting in a higher turbidity. However, the volume of the solution is still significantly smaller than the standard measurement of 1L for turbidity. This option is incorrect.
Therefore, the correct answer is option a) 1mg of fine silica dissolved in 1L of distilled water. This option provides a reasonable amount of silica particles in the standard measurement of 1L, resulting in a turbidity equivalent to 1 JTU.
