A water sample has ppm level concentration of following anions. F^(-)

1.	A water sample has ppm level concentration of following anions. F^(-) = 10, SO_(4)^(2-) = 100, NO_(3)^(-) = 50 The anion/anions that make/makes the water sample unsuitable for drinking is/are……..
Answer» only `NO_(3)^(-)` both `SO_(4)^(2-) and NO_(3)^(-)` only `F^(-)` only `SO_(4)^(2-)` Solution :ACCEPTED amount of negative ion in sample of WATER For `F^(-)` up to 1 ppm `NO_(3)^(-)` up to 50 ppm `SO_(4)^(2-)` up to 500ppm
