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 `F^(-)` only `SO_4^(2-)` only `NO_3^(-)` both `SO_4^(2-) and NO_3^(-)` SOLUTION :only `F^(-)`
