what ions are present in molten lead bromide?
80
Molten lead bromide, PbBr 2(l), is an electrolyte. During electrolysis: Pb 2+ ions gain electrons at the cathode and become Pb atoms. Br - ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.

On rapid cooling, lead iodide falls out of solution quickly, with tiny sparkly flecks of crystals being formed. The solution that cools slowly produces distinctly larger crystals.

MgBr2 is an ionic compound, consisting of Mg2+ and Br1-. To determine if it is a strong electrolyte we must first determine if it is soluble in water. Looking at solubility rules, we can see that all bromides (Br1-) are soluble and that Mg2+ is not an exception. Therefore MgBr2 is a strong electrolyte.

(a) Lead (II) chloride reacts with Cl2 to give PbCl4. (b) Lead (IV) chloride is highly unstable towards heat. (c) Lead is known not to form an iodide PbI4. (i) This is because lead is more stable in +2 oxidation state than in +4 oxidation state due to inert pair effect.

CHEBI:85364 - ammonium bromide An ammonium salt composed of ammonium and bromide ions in a 1:1 ratio. Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water.

Explanation of Solution It is an ionic compound. Lithium is a metal which has a tendency to donate electrons, and bromine is a non-metal which has a tendency to accept electrons. In order to attain stability, lithium (Li+) donates one electron to bromine (Br-) and forms an ionic bond. It is a molecular compound.

The fuse material is mainly made of low melting point alloys such as aluminum antimony alloy. The fuse must be easily melted metal wire in order to fuse in time when the current is large and play a protective role, so usually lead antimony alloy wire is used.

Answer: Tin and lead alloy The fuse wire is made up of Sn (tin) and Pb (lead) alloy because of its high resistance and low melting. Point. The tin and lead alloy is a eutectic composition consisting of 62% and tin plus 38% lead, which melts at 1830C.

Lead(II) chloride (PbCl2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.

Answer: Pb has an electronic configuration of [Xe]6s2 4f14 5d10 6p2. Pb2+ would then have an electronic configuration of [Xe]6s2 4f14 5d10 since Pb2+ means that it lost two of its electrons.

2. a) PbCl4 is bonded covalently with a single shared pair of electrons between each chlorine and the lead atom. PbCl2 can be thought of as ionic and is held together by attractions between Pb2+ ions and Cl- ions.

Elementary lead does not dissolve in water under normal conditions (20oC, and pressure = 1 bar). It may however occur dissolved in water as PbCO3 or Pb(CO3)22-. ... Lead compounds are generally soluble in soft, slightly acidic water.

Silver bromide is insoluble in water and form a pale yellow precipitate in water. If it is explained in other way, you can see a pale yellow color solid is deposited at the bottom of the aqueous solution. You can verify AgBr's solubility by checking the solubility value and solubility product value.
