What do you observe when excess sodium hydroxide is added to lead nitrate solution?

Answer: Lead nitrate solution is treated with sodium hydroxide solution drop wise till it is in excess. Addition of sodium hydroxide to lead nitrate solution initially gives white precipitate which solublizes in excess of N a O H NaOH NaOH added.

What do you observe when sodium hydroxide is added drop by drop to calcium chloride solution?

(a) Sodium hydroxide on reaction with calcium salt gives a milky white precipitate, while that of with lead it gives chalky white precipitate. (b) Sodium hydroxide and ammonium hydroxide on reaction with lead salt gives brown coloured precipitate, while that of with zinc it forms white gelatin like precipitate.

What happens when excess NaOH is added?

By adding an excess amount of sodium hydroxide the formed metal hydroxide precipitate is going to soluble.

What do you observe when ammonium hydroxide solution is added to calcium nitrate solution?

Answer: Complete answer: When ammonium hydroxide is added to calcium nitrate, no reaction or formation of precipitate is seen. An excess of ammonium hydroxide also does not show any results.

What will you observe when excess sodium hydroxide is added to ammonium sulphate solution?

A white gelatinous precipitate is formed which is soluble in excess of sodium hydroxide.

What do you observe when sodium hydroxide solution is added to ferrous sulphate solution?

When ferrous sulfate reacts with sodium hydroxide, dirty green gelatinous ppt. of ferrous hydroxide is formed along with colorless sodium sulfate.

What would you see when sodium hydroxide solution is added drop by drop to tap water containing Aluminium ions?

A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added: the aluminium hydroxide precipitate dissolves to form a colourless solution.

Is calcium soluble in excess NaOH?

It partially ionizes in aqueous solution to form low concentration of hydroxide ions. Since concentration of hydroxide ions is low, calcium hydroxide remains soluble.

What happens when excess of ammonium hydroxide solution is added?

On addition of ammonium hydroxide solution to lead nitrate, white precipitates of lead(ll) hydroxide are formed which redissolves in excess of ammonium hydroxide solution.

What do you observe when sodium hydroxide is added in small amount and in excess to zinc sulphate solution?

white precipitate
Thus, when sodium hydroxide is added drop wise until in excess to a solution of zinc sulphate it is observed that white precipitate is formed which is soluble in excess of sodium hydroxide.

What is observed when sodium hydroxide is added to iron III sulphate solution?

A reddish brown precipitate of Fe(OH)3 is formed.

What will you observe when a little amount of NaOH solution is added to ferrous chloride solution?

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

What happens if excess sodium hydroxide solution is added to samples?

However, if excess sodium hydroxide solution is added: This means that using sodium hydroxide can give a positive result for aluminium ions, but it cannot distinguish between calcium and magnesium ions. A green precipitate forms when dilute sodium hydroxide solution is added to a sample in solution.

What happens when sodium hydroxide reacts with aluminium ions?

A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added: This means that using sodium hydroxide can give a positive result for aluminium ions, but it cannot distinguish between calcium and magnesium ions.

What happens when NaOH reacts with Ca(NO3)2?

At MBA IIM Calcutta According to the analytical chemistry NaOH when reacted with Ca (NO3)2 it forms a white precipitate of Ca (OH)2 and this is insoluble one. It is an observation laid down and usefull in categorizing cations

Can sodium hydroxide distinguish between calcium and magnesium ions?

This means that using sodium hydroxide can give a positive result for aluminium ions, but it cannot distinguish between calcium and magnesium ions. A green precipitate forms when dilute sodium hydroxide solution is added to a sample in solution. Identify the metal ion present in the original solution.
