Calcium by itself is not considered an antioxidant like zinc and selenium. However, while calcium travels through the human digestive tract, it combines with other atoms to form molecules that function as antioxidants. People who swallow any amount of calcium carbonate enjoy a lower risk of death from colorectal cancer compared to people who don't swallow any calcium supplements. However, after absorption into the human blood stream, calcium, in excess, has been shown to cause damage to cardiovascular health and prostate health. Swallowing one 600mg calcium carbonate tablet daily seems to be the optimal dosage for cancer, Heart disease, and bone health. By contrast, iron, copper, manganese, and aluminum are pro-oxidant metals that will, in excess, cause great damage to every cell in our bodies and increase our risk of death from heart disease, cancer, and a dozen other killer diseases.
oxidation if the losing of electrons...therefore the calcium is losing electrons therefore chlorine is the oxidizing agent
No , element calcium is a reducing agent because it donates two electrons and gets oxidized itself.
chlorine oxidizes calcium
No.
it is both oxidizing as well as reducing agent
It is a strong oxidizer, yes.
An oxidizing agent supplies oxygen, and a fuel consumes oxygen.
An oxidizing agent oxidizes the reducing agent, while the reducing agent reduces the oxidizing agent. In simple terms, both processes occur simultaneously. Oxidizing is defined as: the gain of oxygen, loss of hydrogen or loss of electrons. E.g.: C + O2 -> CO2 In this case oxygen would be the oxidizing agent as it supplies oxygen to the carbon. Similarly carbon would be the reducing agent in this case.
The effect of replacing iodine with other oxidizing agents is that the substance being stained will not be stained. Iodine is the only oxidizing agent to dye the material.
Nitrogen is not an oxidizing agent.
The oxidizing agent is oxygen.
Sodium chloride is not an oxidizing agent.
The name of the compound of chemical formula Ca(MnO4)2 is calcium permanganate. Calcium permanganate is an oxidizing agent, but is non combustible.
it is both oxidizing as well as reducing agent
oxygen is the oxidizing agent in both corrosion and combustion
It is a strong oxidizer, yes.
An oxidizing agent supplies oxygen, and a fuel consumes oxygen.
Yes, ozone is a good oxidizing agent. It is because ozone is unstable and releases it's oxygen atom easily.
no
relationship between oxidation and oxidising agent in a redox reaction
An oxidizing agent oxidizes the reducing agent, while the reducing agent reduces the oxidizing agent. In simple terms, both processes occur simultaneously. Oxidizing is defined as: the gain of oxygen, loss of hydrogen or loss of electrons. E.g.: C + O2 -> CO2 In this case oxygen would be the oxidizing agent as it supplies oxygen to the carbon.
