Potassium iodide (KI) is a salt that can help protect you from radioactiveiodine. Yourthyroid glandis the part of your body that’s most sensitive to radioactive iodine. Potassium iodide can help block yourthyroidfrom absorbing radioactive iodine if you are exposed to it. But the salt doesn...
Low potassium diet High sodium diet Caffeine consumption Standing for long periods Rigorous activity Summertime heat Despite the commonality of swelling during pregnancy, some occurrences should be more concerning than others. If you experience sudden swelling of the face and hands, you might want to...
Iodized salt, which has been enriched withpotassium iodideto supply healthy levels of iodine, is the second variety that is equally as common as regular salt. As a type of fortified table salt,the exact concentration of iodine and other compounds like dextrose differ. There is also doubly forti...
Does a reaction occur when aqueous solutions of chromium (II) nitrate and potassium hydroxide are combined? If a reaction does occur, write the net ionic equation. What is the chemical equation for salt formation? Explain how to prepare a...
The reference electrode/system and the hydrogen ISE (i.e. the electrode with the glass membrane) can be separate electrodes or they can be combined into a single electrode for convenience. The combination-style electrode is very common.
Explain what happens when concentrated hydrochloric acid (HCl) is added to a saturated solution of potassium chloride (KCl). Explain the role of the boiling chips during reflux and distillation. If the tongs used in the experiment were made of pure iron, what might ha...
chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other ...
for domestic use it is fined down to what is known as table-salt‚ and small quantities of other chemicals are added to it to keep it free-flowing when in contact with the atmosphere. Salt and potassium are combined to produce iodised salt‚ used when iodine is lacking in diet. It’...
What is the chemical make up of salt? Explain what happens when concentrated hydrochloric acid (HCl) is added to a saturated solution of potassium chloride (KCl). Why does saltwater freeze, but salt is used to melt ice? How is a mixture of water and salt separated?
