The chemical formula KBr is an ionic compound (made from a metal and a non-metal). K represents the metal potassium, and Br represents bromine (a non-metal halogen). The proper chemical name is potassium bromide.
To balance the equation K + Br₂ → KBr, you need to make sure the number of atoms of each element is the same on both sides of the equation. To balance this equation, you need to put a coefficient of 2 in front of KBr. This way, you will have 2 potassium atoms, 2 bromine atoms, and 2 KBr molecules on both sides of the equation.
The oxidation number of K (Potassium) in KBr (Potassium Bromide) is +1. This is because alkali metals like Potassium typically have an oxidation number of +1 in compounds.
Easy...the periodic table gives the average mole weight of each element averaged out over all it's naturally occurring, if any, isotopes, i.e., K is 39.09 Br is 79.9 Add them up and it's (to three significant figures): So KBr is 119 g/mole
Bromine (Br) forms anions in potassium bromide (KBr). It gains one electron to attain a full outer electron shell and achieve a stable electronic configuration.
To prepare a 0.01N KBr solution, dissolve 0.74g of KBr in 1 liter of water. This will give you a solution with a molarity of 0.01N for KBr.
