What happened when NaOH was added to the copper II sulfate pentahydrate solution?
What happened when NaOH was added to the copper (II) sulfate pentahydrate solution? A blue precipitate formed.
What do you observe when dilute sodium hydroxide is added to copper II sulfate solution?
On adding sodium hydroxide to copper sulphate solution, a pale blue precipitate of copper hydroxide is formed which is insoluble in excess of sodium hydroxide.
Does sodium hydroxide react with copper?
All Answers (11) Dear Wei Jyun Wang corrosion of metallic copper does indeed take place in the presence of sodium hydroxide solutions.
What would you see when sodium hydroxide is added to 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.
Which two solutions are added to test for the presence of sulphate ions?
Testing for sulfate ions Sulfate ions in solution, SO 4 2 -, are detected using barium chloride solution. The test solution is acidified using a few drops of dilute hydrochloric acid, and then a few drops of barium chloride solution are added. A white precipitate of barium sulfate forms if sulfate ions are present.
Which metallic hydroxide is soluble in excess Naoh?
Tin
Which is soluble in NaOH?
Water
Which metal hydroxide is least soluble in water?
Hence, Be(OH)2 is the least soluble in water.
Is sodium hydroxide soluble or insoluble?
Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition, and with a boiling point of 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol. NaOH is insoluble in ether and other non-polar solvents.
