Which of the following are correclty matched with their standard upper limit.
Fe 0.2 ppm
Mn 0.05 ppm
Nitrate 50 ppm
Cd 50 ppm
Pb 50 ppm
Fluoride 1 ppm
Sulphate 500 ppm
Answer:
5
Solution:
Fe (0.2 ppm), Mn (0.05 ppm), Nitrate (50 ppm), Fluoride (1 ppm), and Sulfate (500 ppm) are all perfectly matched with their standard upper limits. Pb (Lead) and Cd (Cadmium) are incorrectly matched because their safe upper limits are much lower ( or for Lead, and for Cadmium). Therefore, exactly 5 parameters are correctly matched, making the final answer 5.00.
