What else can I help you with?
What substance is present in FeCl3 that gives a purple color?
Quite many compounds. Phenols are one of the most common group of compounds here. In other words: any compounds containing benzene ring connected to OH group will give you purple color when treated with FeCl3. It seems that if you have FeCL3 sample it is probably impurified by phenolic compounds.
Is FeBr3 a base or an acid?
Since Fe+ is more reactive than H+, I would guess that it is slightly acidic, but let me look that up for you... Yep. It will react with water to form a solution of a strong acid, hydrobromic acid, and a pretty weak base, iron(III) hydroxide (Which is actually weak because it forms FeO(OH).H2O, iron(III) oxide hydroxide hydrate.)
What is the formula for titanium ii phosphite?
The chemical formula for titanium (II) phosphite is Ti3(PO3)4. In this compound, titanium has a +2 oxidation state, denoted by the Roman numeral II in parentheses. Phosphite is a polyatomic ion with the formula PO3, and the subscript 4 indicates that there are four phosphite ions in the compound.
Have a chemical FeCl4- and you add NaCl?
1. FeCl4 doesn't exist. 2. Any reaction occur between sodium chloride and iron chlorides.

When does iron show the 4th oxidation state?
Never. iron shows either +2 or +3 oxidation state but in Fe3O4 its oxidation state is seems to +4 but it is actually mixture of one moles FeO and one mole Fe2O3 , (FeO.Fe2O3 = Fe3O4).

Are there liquids affected by magnetism?
Ferrofluid is a colloid of iron particles in water or oil. It flows like a liquid but sticks to magnets. Magnetorheological fluid is a liquid that will harden when in the presence of a magnetic field. There are also paramagnetic fluids which are attracted to magnets. Manganese(II) chloride or copper(II) sulfate dissolved in water, for example. A scientist in Japan made a very paramagnetic liquid [bmim]FeCl4 "by mixing 1-butyl-3-methylimidazolium chloride ([bmim]Cl) and FeCl3". Any liquid that is conducting an electric current will be affected by magnetism as well, which is the basis of magnetohydrodynamics and the "caterpillar drive" of submarines.
