What elements make up potassium iodide?

A molecule of potassium iodide consists of one potassium cation and one iodide anion, which are held together by an ionic bond.

What elements is potassium iodide made of?

Potassium Iodide is a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties.

How do you make potassium iodide?

Potassium iodide (KI) is prepared by reacting iodine with a hot solution of potassium hydroxide. It is mainly used in the form of a saturated solution, 100 g of potassium iodide to 100 ml of water. This equates to approximately 50 mg/drop. The solution is usually added to water, fruit juice or milk before drinking.

What is the formula used for potassium iodide?


Potassium iodide’s chemical formula is KI, where K is potassium and I is iodine. It is an ionic compound and each potassium ion has a charge of +1, while each iodine ion has a charge of -1.

What elements make up iodide?

What elements make up the compound potassium nitrate?

Potassium nitrate, also known as saltpeter or niter, is a chemical compound consisting of potassium, nitrogen, and oxygen.

Is potassium a compound or element?

potassium (K), chemical element of Group 1 (Ia) of the periodic table, the alkali metal group, indispensable for both plant and animal life.

How do you make iodine?

Youtube quote:Now check this new volume and measure out separately five times more of 3% hydrogen peroxide. Now take the mixture and add it to nitrogen peroxide will instantly start forming iodine.

What is the chemical formula for the iodide ion?


The chemical iodide formula is KI or I−. It is that the ion I−. Compounds with it in formal oxidation number −1 are iodides.

What group is the element iodine in?

How do you make iodine crystals?

Youtube quote:So we swirl those together to nick's thing. And then we take some hydrogen peroxide. Which is just drugstore three percent hydrogen peroxide. We could use any number of other oxidizers.

How do you make iodine from seaweed?

Dried Laminariaceae seaweed contains a high proportion of iodine. After burning off the organic matters, the ash that remained is boiled with deionized water to dissolve the iodide ions. The iodide ion is oxidised by acidified hydrogen peroxide solution to iodine.

How do you make lugol’s iodine?

Dissolve KI in about 20-30 ml of distilled water. Add iodine and heat gently with constant mixing until iodine is dissolved. Dilute to 100 ml with distilled water. Store in amber glass-stoppered bottle in the dark.

Is iodine crystals a element or compound?

Answer and Explanation: Iodine crystals are a pure substance because they are composed entirely of the element iodine.

Why is iodine an element?

Although it is technically a non-metal, it exhibits some metallic qualities. Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements.
