Water and carbon dioxide are waste products released as a direct result of materials
Answer:
HCN - Hydrogen cyanide The conjugate acid of CN- is HCN. HCN stands for hydrogen cyanide. The conjugate acids are a combination of a strong acid and a low base.
Answer : The concentration of are 0.127 ppm, 0.127 ppm and 0.254 ppm respectively.
Explanation : Given,
Mass of =
Volume of solution = 2.25 L
First we have to calculate the concentration in terms of g/L.
conversion used :
As we know that,
1 mg/L = 1 ppm
0.127 mg/L = 0.127 ppm
So, the concentration will be 0.127 ppm.
The concentration of in ppm is, 0.127 ppm.
Now we have to calculate the concentration of and .
We assume that, dissociates 100 % in the solution then the balanced reaction will be:
From the reaction we conclude that the mole ratio of is, 1 : 1 : 2. So,
The concentration of = 0.127 ppm
The concentration of = 2 × 0.127 ppm = 0.254 ppm
