What would you observe when a blue litmus is introduced into a solution of hydrogen chloride gas?
Answer Expert Verified HCl is Acidic in nature. This, when the Hydrogen chloride aolution is added to the Blue litmus. Then, blue litmus will turns into red showing the acidic nature of the Hydrogen chloride gas.
What is the action of litmus on ferric chloride?
Solution of ferric chloride is acidic; therefore, blue litmus will change to red in this solution.
What Happens When A is added to blue litmus solution?
On adding blue litmus solution to both the test tubes, the colour of the test tube A will change from blue to red. This is because HCl is acid and acids turn blue litmus to red.
What will you observe when I blue litmus paper is introduced into a solution of sodium carbonate?
red
Since the acid is strong, the solution will be acidic. Therefore, the colour of blue litmus will change to red.
What does Blue litmus observe?
Blue litmus will turn into red which will indicate the solution to be acidic.
What will you observe when red litmus is introduced into a solution of sodium sulphate?
i Solution of Na2SO4 is neutral therefore no colour change will be observed when red litmus paper is introduced in thus solution.
What happens when red litmus is introduced into a solution of sodium sulphate?
Explanation: 1. When red litmus is introduced in solution of sodium sulfate, the color changes to blue in red litmus paper because sodium sulfate is a base.
Why is a solution of ferric chloride is acidic?
An aqueous solution of FeCl3 salt undergoes hydrolysis and forms HCl. This strong acid releases H+ ions in the solution. Hence, the resulting solution is acidic and turns blue litmus turns red.
What colour change will you observe when blue litmus solution is added to?
Red
Acids turn blue litmus red. Bases do not change the colour of blue litmus. Acids do not change the colour of red litmus. Bases turn red litmus blue….Ans.
| Solution | Color of litmus solution |
|---|---|
| Acidic | Red |
| Basic | Blue |
| Neutral | No change |
What change in colour will you observe when blue litmus paper is added to each test tube write change in colour for each test tube?
| Test tube | Effect on blue litmus | Effect on red litmus |
|---|---|---|
| A | Changes to red | Remains red |
| B | Remains blue | Changes to blue |
| C | Remains blue | Remains blue |
What happens when blue litmus paper is added to the following sodium bicarbonate?
Answer: There will no change in blue litmus paper. Explanation: As we know baking soda is base so blue litmus paper remains blue.
Why does the colour of red litmus turns into blue in above observation?
Mechanism. Red litmus contains a weak diprotic acid. When it is exposed to a basic compound, the hydrogen ions react with the added base. The conjugate base formed from the litmus acid has a blue color, so the wet red litmus paper turns blue in alkaline solution.
What happens when a blue litmus paper is introduced in ferric chloride?
As it is an acidic solution, the color of the blue litmus changes to red when the litmus paper is introduced in ferric chloride solution. What would you observe when a blue litmus is introduced into a solution of hydrogen chloride gas?
Is ferric chloride an acid or a base?
The ferric chloride is the acidic solution as it is formed due to the interaction of weak base iron oxide ( ) and strong acid hydrochloric acid (HCl). As it is an acidic solution, the color of the blue litmus changes to red when the litmus paper is introduced in ferric chloride solution.
What happens when calcium carbonate reacts with dilute HCl?
A substance X is used as a building material and is insoluble in water. When reacted with dilute HCl, it produces a gas which turns lime water milky. Predict the substance. Write the chemical equations involved. The substance is probably calcium carbonate (CaCO 3 ). also called lime stone or marble.
