Describe how you would distinguish between solutions NH4Cl and NaCl using litmus paper
All is right
To distinguish between solutions of NH4Cl and NaCl using litmus paper, follow these steps:
Step 1: Obtain small samples of the NH4Cl and NaCl solutions.
Step 2: Take a piece of litmus paper. Litmus paper is typically red or blue. Red litmus paper turns blue in the presence of a base, while blue litmus paper turns red in the presence of an acid.
Step 3: Dip one end of the litmus paper into the NH4Cl solution and observe any color changes. Note down the result.
Step 4: Rinse the litmus paper with distilled water to remove any residue from the previous solution.
Step 5: Dip the same end of the litmus paper into the NaCl solution and observe any color changes. Note down the result.
Step 6: Compare the color changes observed in both solutions.
If the litmus paper turns red in both solutions, it indicates the presence of an acid. This means that both NH4Cl and NaCl are acidic solutions.
However, if the litmus paper turns blue in the NH4Cl solution and remains unchanged (red or blue) in the NaCl solution, it suggests that NH4Cl is a basic solution while NaCl is neutral or slightly acidic.
Remember that litmus paper is a general indicator and cannot differentiate between weak acids, strong acids, or specific bases. It only gives a rough indication of the solution's acidity or basicity based on the observed color change.
To distinguish between NH4Cl (ammonium chloride) and NaCl (sodium chloride) using litmus paper, you can follow the steps below:
1. Take two separate test tubes and label them as Solution A and Solution B.
2. Pour a small amount of Solution A (NH4Cl) into the test tube labeled Solution A, and Solution B (NaCl) into the test tube labeled Solution B.
3. Obtain a piece of red litmus paper and a piece of blue litmus paper.
4. Dip the red litmus paper into Solution A (NH4Cl) and observe the color change. If the litmus paper turns blue or stays the same, it indicates that Solution A is basic or neutral.
5. Next, dip the blue litmus paper into Solution A (NH4Cl) and observe the color change. If the litmus paper turns red, it indicates that Solution A is acidic.
6. Repeat steps 4 and 5 with Solution B (NaCl) using fresh litmus papers.
7. If Solution B does not cause any color change in the litmus papers, it indicates that Solution B is neutral.
By comparing the results, if Solution A turned the red litmus paper blue or remained unchanged, while Solution B did not cause any color change in the litmus papers, you can conclude that Solution A (NH4Cl) is basic and Solution B (NaCl) is neutral.
NaCl is neutral in solution and the other compound will not be neutral. Distinguish between NH4Cl and NaCl?NH4Cl is one of the few chemicals that sublime on heating; NaCl doesn't. Warm with sodium hydroxide solution. NH4Cl gives strong smell of ammonia. Gas is alkaline. No result with NaCl.
Equation: NH4Cl + NaOH ---> NaCl + H2O + NH3
Hoped that helped :)
