Which statement is true for a solution when its concentration of hydroxide ions increases? It becomes more acidic. It becomes le
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
When we increase the concentration of a substance then it means we are increasing number of molecules of the substance. So, when there is increase in concentration of hydroxide ions the it means there are more number of ions into the solution.
Also, it is known that pOH =
Since there is increase in concentration so, this means that there will be decrease in the value of pOH.
Also, pH + pOH = 14
so, pH = 14 - pOH
pH = +ve
Thus, we can conclude that there will be increase in the value of pH.

Answer:
The solution to the given problem is done below.
Explanation:
a)
i) =( 0.002 μg / L )( 1mg / 1000 μg )( 1L / kg )( 1000 mil / 1 billion) = 0.002 ppb
ii) =( 0.002 μg / L )( 1mg / 1000 μg )( 1L / kg )( 1,000,000 mil / 1 trillion) = 2 ppt
iii) =( 0.002 μg / L )( 1 mole / 540g ) = 3.7 x μM.
b)
i) =( 0.002 μg / g ) = 0.002 ppm
ii) In solids, ppb = μg/kg
=( 0.002 μg / g )( 1000 mil/ 1 billion) = 2 ppb
