Why does hydrogen iodide in an aqueous solution conduct an electricity?
Hydrogen iodide is dissociated in water.
What is the test for hydrogen iodide?
Hydrogen iodide can be tested using silver nitrate solution. When hydrogen iodide is bubbled through silver nitrate solution, a yellow precipitate of silver iodide is formed. This confirms the presence of iodide ions in the sample.
What is compound HI?
Compound HI is hydrogen iodide, which is a binary compound formed from hydrogen and iodine. It is a colorless gas at room temperature and is highly reactive. Hydrogen iodide is commonly used in organic chemistry reactions as a source of iodide ions.
Acid formed when hydrogen iodide dissociates in an aqueous solution?
Hydroiodic acid (HI) is formed when hydrogen iodide (HI) dissociates in an aqueous solution. It is a strong acid that ionizes completely in water to yield hydronium ions (H₃O⁺) and iodide ions (I⁻).
How many ions in calciom iodide?
Calcium iodide is an ionic compound composed of one calcium ion (Ca2+) and two iodide ions (I-). Therefore, there are a total of 3 ions present in calcium iodide.
Who of the following is not a strong electrolyte hydrogen chloride hydrogen fluoride hydrogen bromide hydrogen iodide?
Hydrogen fluoride is not a strong electrolyte. This is because it does not fully dissociate into ions when dissolved in water, unlike hydrogen chloride, hydrogen bromide, and hydrogen iodide.
Why is the addition of concentrated sulfuric acid to solid potassium iodide unsuitable for the preparation of hydrogen iodide?
The reaction between concentrated sulfuric acid and solid potassium iodide does not produce hydrogen iodide. Instead, it generates sulfur dioxide gas, potassium sulfate, and iodine. Therefore, this reaction is unsuitable for obtaining hydrogen iodide.
What is represented by HI(aq)?
This is a water solution of hydrogen iodide which make hydroiodic acid. That is, HI(aq) means HI aqueous which is hydroiodic acid.
How many barium ions are there in 250 mL of a barium iodide solution that has an iodide ion concentration of 0.125 M?
The number of barium ions is 0,188.10e23.
Why is the reaction between hydrogen iodide and water acidic?
I am a little unsure of your question. Reactions can't be acidic, but solutions can be. When HI dissolves it dissociates into ions. (H+ and I-) An acid is defined as a donor of H+ so HI dissolved in water is acidic
How many unshardd pairs of electrons are in a molecule of hydrogen iodide?
There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
Why do you think no reaction occurs between acidified hydrogen peroxide and halide ions other than iodide?
No reaction occurs between the acidified hydrogen peroxide and the other halide ions, because the hydrogen ions involved in both cases are in the same group. For a reaction to occur it needed to have an element that is more reactive than hydrogen.
