What happens when iron react with sodium hydroxide?

to form a green precipitate. Hint: We know that the green precipitate is of iron (II) hydroxide and the brown precipitate is of iron (III) oxide. … Now we have to find out which iron salts react with sodium hydroxide to form iron (II) hydroxide and iron (III) hydroxide.

How does iron react with sodium hydroxide?

Reaction of iron(II) ions with NaOH – YouTube

What colour precipitate will a solution of iron III ions turn when sodium hydroxide is added?

Adding sodium hydroxide to a solution containing iron(II) ions (Fe+2) will produce a green precipitate. A brownish-red precipitate will be formed if iron(III) (Fe+3) reacts with sodium hydroxide.

What do you observe when sodium hydroxide solution is added drop wise till in excess to a solution of ferric chloride?

Black precipitate is formed which is soluble in excess of sodium hydroxide.

What change do you observe if ferrous chloride and ferric chloride reacts separately with sodium hydroxide?

Answer: When sodium hydroxide is added to ferric chloride solution,a reddish brown precipitate is formed

What do you observe when sodium hydroxide is added to a solution of ferric chloride write equation for the reaction taking place?

FeCl3+3NaOH⟶Fe(OH)3(s)+3NaCl.

Why does zinc hydroxide dissolved in excess sodium hydroxide?

Zn(OH)2 is amphoteric, so it can reacts with the excess NaOH. Zinc hydroxide will dissolve because the ion is normally surrounded by water ligands, when there is excess sodium hydroxide, the hydroxide ions displace the water ligands and the complex will acquire a −2 charge, making it soluble.

What happens when sodium hydroxide solution is added to zinc nitrate solution?

Answer: when sodium hydroxide solution is added to a solution of zinc nitrate, a white precipitate of zinc hydroxide will be formed by double displacement.

What happens when sodium hydroxide reacts with zinc hydroxide?

Bases also react with certain metals, like zinc or aluminum, to produce hydrogen gas. For example, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas. Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g).

Whats the product of FeSO4 AQ BaCl2 AQ?

When phenolphthalein indicator is added to sodium hydroxide solution the colour of the solution turns pink the pH of this solution is?

It is colourless below pH 8.5 i.e. in acidic solutions and attains a pink to deep red hue above pH 9.0 i.e. in basic solutions. Therefore, when phenolphthalein is added to caustic soda which is a strong base, it turns pink in colour.

Why do precipitation reactions occur?

Formation of an insoluble compound will sometimes occur when a solution containing a particular cation (a positively charged ion) is mixed with another solution containing a particular anion (a negatively charged ion). The solid that separates is called a precipitate.

What happens when you add sodium hydroxide solution to copper II ions?

Hydroxide ion (OH) binds to the copper (II) ion even more strongly than does water. As a result, hydroxide ion can displace water from the copper (II) ion, yielding copper hydroxide, Cu(OH)2, a blue precipitate.
