Question 34
ESMCQ2 marksNeeds review
The characteristics of a water sample are as follows: Na⁺ = 92 mg/L, K⁺ = 19.5 mg/L, Ca²⁺ = 40 mg/L, and Mg²⁺ = 24 mg/L. What is the sodium adsorption ratio (SAR) of the water sample which may be considered for irrigation purposes?
[Atomic weight (g/mol): Na = 23, K = 39, Ca = 40, and Mg = 24]
