Colourless solution. most coloured solutions contain transition metal ions
Two Na plus ions will combine with an O2- to form the basic compound sodium oxide. When water is further added, the neutral salt, sodium hydroxide is formed.
In the Periodic Table of elements you have elements, these elements represent neutral atoms of elements, ions are just like neutral atoms, the only difference is the have less or more electrons in the orbital. So Na is sodium atom and Na+ is sodium ion
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
Some examples of insoluble bromide compounds include silver bromide (AgBr), lead(II) bromide (PbBr2), and mercury(I) bromide (Hg2Br2). These compounds do not dissolve easily in water and form solid precipitates when bromide ions are combined with the corresponding metal ions.
Sodium bromide is an ionic solid consisting of a 1:1 ratio of Na+ and Br- ions arranged in a cubic lattice. The coordination number is 6 , which means each sodium ion is surrounded by 6 bromine ions and each bromine ion is surrounded by 6 sodium ions. [Na]+ [Br]-
Sodium bromide is an ionic substance. It conducts electricity when melted or when dissolved in water. This is due to the sodium, Na+ ions and the Br- ions present. It does not conduct electricity in the solid state as the ions can not move.
The compound sodium bromide is formed by the formation of ionic bonds between sodium and bromide ions.
Sodium bromide dissassociates into Na+ and Br- ions when it is dissolved in water.NaBr + H2O = Na+ and Br- aq.
HBr(aq)+ NaOH(aq)---> HOH(l)+ NaBr(aq) or sodium hydro bromide and hydroxyl ions
The atomic ratio Sr/Br is 2.
1:1
Don't react, all giving soluble ions.

Add silver nitrate solution to a solution of bromide ions. A pale yellow precipitate of silver bromide formed indicates the presence of bromide ions.

The major ions in sea water are chloride, sodium, sulphate, magnesium, calcium, potassium, bicarbonate, bromide, strontium,boron and flouride.
