Does potassium iodide melt easily when heated?
Potassium iodide, like salts in general, has a high melting point. It does not melt easily when heated.
How do you make potassium polysulfide?
reduction od potassium sulfate by reducing agents such as hydrogen and carbon monoxide at high temperature.
What is the yellow powder made from lead nitrate and potassium iodide used for?
You must be thinking of the classical precipitation reaction done in many freshmen chemistry science labs, the mixture of lead nitrate and potassium iodide: * Pb(NO3)2(s) + 2 KI(s) → PbI2(s) + 2 KNO3(s) The precipitate, lead (II) iodide (PbI2) is a toxic, yellowish solid. Lead iodide is toxic due to its lead content. It displays a range of colors with varying temperature from bright yellow at room temperature to brick red. On cooling, its color returns to yellow. Currently, it only finds use in its crystalline form, where it is used as a detector material for high energy photons including x-rays and gamma rays. In the nineteenth century it was used as an artists' pigment under the name Iodine Yellow, but it was too unstable to be useful.

Is potassium iodide ionic or molecular?
Potassium is K1+, and Iodine is I1-. As a result, Potassium iodide is made. It's ionic becuase Potassium has a positive charge, so it needs one more electron to have its orbitals filled. Iodine on the other hand, has an electron that isn't needed. If Iodine can give up its electron, then all of its orbitals will be filled. As a result, iodine gives it's extra electron to the potassium, and they both have filled orbitals. When an electron is being given and accepted, that's called an ionic bond. So Potassium iodide is ionic.

Yes, to an extent of about one-fifth of the (high) solubility of lithium iodide in water.
