Where to get potassium iodide?

You can order potassium iodide online from Its white crystals are soluble in water, alcohol or glycerol.
Some information by our algorithm and check these resources as below:

Is potassium iodide iodide ionic or covalent?

Potassium iodide would be classified as with or to a non-metal the bonding is considered ionic (electron/s transferred from metal to non-metal). When two or more non-metals are bonded together the bonds are considered covalent (shared electrons). Metalic occurs when two or more metals are bound together ionic. If you look at a periodic into metals and non-metals (and inbetween are some elements that circumstance called the semi-metals or metalloids). When a metal is bonded can be either depending on table the elements are divided.

why is potassium iodide used in iodometric titrations instead of sodium iodide?

Potassium iodide is available in a purer form than sodium iodide. NaI will work, but you’ll get more accurate results if you use KI.

What is formula for potassium iodide?

KI is the formula for potassium iodide

chemical equation needed for mixing potassium iodide, potassium iodate and sulfuric acid?


Find the balanced redox equation when potassium iodide solution reacts with acidified potassium dichromate?

The redox reaction isI- + KCr2O7 —-> I2 + Cr3+K disappears or isn’t included because it doesn’t take part in the reaction. It’s oxidation state doesn’t change and only I and then I’ll just give each half reaction make a half reaction you Cr oxidation states change. Since you know, I assume you know, how to balance redox reactionsIf you take each one and get6 I- —-> 3 I2 + 6e-Cr2O7 2- + 14H+ + 6e ———> 2 Cr3+ + 7H2OThe overall reaction is6I- + Cr2O7 2- + 14H+ —-> 3 I2 + 2Cr3+ + 7H2OThe H+ is what makes the solution acidic.

Formula for potassium iodide?

KI is the chemical formula for potassium iodide. Thank you for the question.

Aqueous potassium iodate (KIO3) and potassium iodide (KI) react in the presence of dilute hydrochloric acid ?

moles KIO3 = 0.0050 x 0.0150 L = 0.000075Moles KI = 0.010 x 0.0300 L = 0.00030KI is the limiting reactant ( 0.000075 x 5 = 0.000375 moles are needed)5 : 3 = 0.00030 : xx = moles I2 = 0.00018Mass I2 = 253.808 g/mol x 0.00018 mol = 0.0457 g

What is the formula for potassium iodide?

The formula for potassium iodide is actually just that, KI, where K stands for potassium, and I for iodide.

how do you distinguish between aqueous potassium bromide and potassium iodide?

The best method is the silver aqueous ammonia solution up7/testing.htmlNOTE: I’ve included the chloride ion to show you that all 3 halogens can be distinguished from nitrate test for chloride, bromide and iodide ions.The test will give:A white precipitate of silver chloride in aqueous ammonia solutionA cream (off white) precipitate of silver bromide with in aqueous ammonia solutionA yellow precipitate of silver iodide with chloride ionsSilver nitrate + sodium chloride As†’ silver chloride + sodium nitrateAgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq)The white precipitate will dissolve quickly bromide ions.Silver nitrate + sodium bromide As†’ silver bromide + sodium nitrateAgNO3(aq) + NaBr(aq) AgBr(s) + NaNO3(aq)The cream precipitate will dissolve slowly with iodide ionsSilver nitrate + sodium iodide As†’ silver iodide + sodium nitrateAgNO3(aq) + NaI(aq) AgI(s) + NaNO3(aq)The yellow precipitate is insoluble in each other.
