when their solution are mixed iron carbonate solid and solution of sodium sulphate is produced..
assuming you mean sodium plus iron II carbonate, the products are iron plus sodium carbonate. iron is a transitional metal which can make +2 or +3 ions, and YOU need to state that in your word equation. there no such thing as iron carbonate, but there is such thing as iron II carbonate and iron III carbonate
Iron Sulphate + Sodium Hydroxide -> Sodium Sulphate (Na2SO4) and Iron Hydroxide (Fe(OH)2)
Both sodium carbonate and iron chloride are ionic compounds that are soluble in water. When dissolved in water, these two compounds will react by trading ions, forming sodium chloride and iron carbonate. This last compound, iron carbonate (either FeCO3 or Fe2(CO3)3, depending upon iron's oxidation state) is insoluble in water, and will precipitate, or crystallize, out of solution.
Sodium displaces the sulfate to make sodium sulfate; iron displaces the hydroxide to make ferrous hydroxide which becomes brown.
dark green (but orange - brown if left standing)
FeSO4 + 2NaOH = Na2SO4(sodium sulphate] + Fe(OH)2 [iron(II) hydroxide / ferrous hydroxide].
Nope, Calcium is stronger then the iron so it keeps its hold on the carbonate

Type II implies a compound of a transition metal such as iron which can have one of a number of oxidation states. Ternary implies a containing three different elements such as sodium carbonate. There are two type II ternary iron sulphates, iron (II) sulphate and iron (III) sulphate. Please see the link.

green solution
Solutions of iron(III) chloride and sodium carbonate will react in a double replacement reaction to produce aqueous sodium chloride and an iron carbonate precipitate, which will collect in the bottom of whatever you're mixing them in. Here's the formula: 2FeCl3(aq) + 3Na2CO3(aq) --> 6NaCl(aq) + Fe2(CO3)3(s). Let is settle for a few hours and you'll have clear salt water up top and a reddish-brown mud at the bottom.
Iron does not displace sodium from a salt solution because it is not reactive enough. Iron does, however, displace Cu from a copper sulphate solution.
Iron oxide + Sulphuric Acid iron sulphate + water
Ferrous (Iron II) and water mixed together. A simple solution of sodium carbonate (baking soda) and water could be used to bring out the invisible ink
