How to distinguish sodium hydroxide solution and ammonium hydroxide solution by a chemical test?
Chemical Test for Solutions Default (GPT-3.5) User How to distinguish sodium hydroxide solution and ammonium hydroxide solution by a chemical test? ChatGPT You can distinguish between sodium hydroxide (NaOH) solution and ammonium hydroxide (NH4OH) solution using a simple chemical test. Litmus Paper Test: Dip a piece of red litmus paper into each solution. Sodium hydroxide (NaOH) is a strong base and will turn red litmus paper blue. Ammonium hydroxide (NH4OH) is a weak base and will also turn red litmus paper blue, but it may do so less vigorously and may take some time. Phenolphthalein Test: Add a few drops of phenolphthalein indicator to each solution. Sodium hydroxide (NaOH) will turn pink or magenta, indicating its strong alkaline nature. Ammonium hydroxide (NH4OH) may turn pink, but it will be less intense, indicating its weaker alkaline properties. Odor Test: Carefully smell the solutions. Ammonium hydroxide (NH4OH) solution has a distinctive, pungent ammonia-like odor, which is not present in sodium hydroxide (NaOH) solution.
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What is the significance of sodium-nitroprusside test?
This test is performed to test the presence of cysteine in the test solution (protein solution)
Describe the test for aluminium ions?
Test: Add aqueus sodium carbonate solution, then warm it. Observation: Formation of white precipitate. Deduction: The presence of aluminum ions, Al3+ Or Test: Observation: Add aqueous sodium hydroxide White precipitate occur Add aqueous sodium hydroxide (excess) & warm White precipitate solute Test with red litmus paper Changes red - blue Deduction: The presence of aluminum ions, Al3+
How do you test for copper ions?
When copper react with sodium hydroxide, copper hydroxide is one of the products which has a distinct colour, so... 1) Add a few drops of dilute sodium hydroxide to the solution you wish to test for copper ions 2) If a blue precipitate forms (copper hydroxide is insoluble in water), then it's likely that copper ions are present 3) To confirm the presence of copper ions, add ammonia solution & if the precipitate dissolves, forming a deep blue solution, you know copper ions are present

What is the major effect of sodium hydroxide on proteins?
The solution will turn violet, you can try this by adding 20 drops of hydroxide solution into a test tube with egg albumin and shaking it carefully.
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
What element is responsible for the cloudy solution in the silver nitrate test?
Sodium - Na. When silver nitrate is mixed with Sodium Hydroxide, Sodium Iodide, Sodium Phosphate a precipitate forms.

What are the steps to do the biuret test?
1) Add 2cm3 of solution to be tested to a test-tube. 2) Add an equal volume of 5% potassium hydroxide* solution and mix. 3) Add 2 drops of 1% copper sulphate solution and mix. A mauve or purple colour develops if protein is present. *Sodium hydroxide solution can be used instead of potassium hydroxide solution.
