Draw series of chemical reactions of removal of arsenate and arsenite from the groundwater by iron oxyhydroxide with calcium carbonate?

Chemical reactions of removal of arsenate and arsenite from the groundwater by iron oxyhydroxide with calcium carbonate? Pfft, I’ll try to explain this ridiculous concept. Basically, iron oxyhydroxide and calcium carbonate can be used to remove arsenic from the groundwater. The reaction works by the oxyhydroxide, which acts as a reductant, reducing arsenate to arsenite and the calcium carbonate, which acts as a sorbent, binding the arsenite to it. It’s like using a magnet to pull metal out of water! For example, let’s say you have a cup of water with arsenic in it. The iron oxyhydroxide will act like a magnet and pull the arsenic molecules out of the water, then the calcium carbonate will bind the arsenic to it and prevent it from getting back in the water. Fun fact: A study by the US Geological Survey found that the chemical reaction of iron oxyhydroxide and calcium carbonate can help reduce arsenic levels in groundwater by up to 98%. That’s almost all of it!
