Which is worse for a plant the sodium or the chlorine ion?

Answer 1

While calcium and magnesium are necessary plant nutrients, only a small amount of sodium is required by plants. Occasional leaching with rainwater or unsoftened water helps lower sodium concentration in soil. Providing good drainage for plants will also prevent sodium from building up in soil. Plants in containers may be re-potted to eliminate sodium build-up as well.

Chlorine is found naturally in small amounts and plants will benefit from trace amounts of this element in water. Chlorine is also added to water systems as a disinfectant and has proven to be toxic to plant life when used in excess. Chlorine can be removed from water by gentle heating, or by allowing treated water to stand in an open container overnight. The chlorine changes to a gas and is released from the water.

However, in excess amt, both sodium and chlorine can destroy the plants. Sodium cause stress to the plants and the leaves dry up and die and burn when exposed to sunlight. Sodium will pull out the water from the plants. Plants like humans need a lot of water. Chlorine will eat up the roots of the plant thus, killing it.

Answer 2

The plant needs a little of each as do animal cells. People get high blood pressure from too much sodium.
You could make the assumption that it might be similar in the plant.

Answer 3

chlorine ion

Answer 4

Na is better than Cl because it is used in various purposes like in water movement etc. but cl is also very useful but not compared to na.
