Show Answer Key & Explanations Step-by-step solution for: CBSE Class 7 Science Acids Bases And Salts Worksheet Set B
The table you provided shows how different natural and synthetic indicators change color when they come into contact with acids or bases. This is a standard reference chart used in chemistry to identify whether a substance is acidic or basic (alkaline) based on the color change of the indicator.

Here’s a quick summary of what each indicator does:

- Methyl orange: Orange normally → Red in acid, Yellow in base
- Phenolphthalein: Colourless normally → Stays colourless in acid, turns Pink in base
- Litmus: Purple normally → Red in acid, Blue in base
- Red Cabbage leaf: Red normally → Stays Red in acid, turns Green in base
- Hydrangea Flower: Blue normally → Stays Blue in acid, turns Pink in base
- Turmeric (Haldi): Yellow normally → Stays Yellow in acid, turns Brownish red in base
- China rose: No colour change normally → Turns Magenta in acid, Green (Dark Pink) in base

This table helps students predict or identify the nature of an unknown solution by observing which color the indicator turns after being added to it.

Since no specific question was asked (like “What color will litmus turn in vinegar?” or “Which indicator stays yellow in acid?”), I’ll assume you want confirmation that this table is correctly interpreted — and yes, it is! All entries match standard chemical behavior for these indicators.

If you have a specific question using this table (e.g., “What color does phenolphthalein turn in soap water?”), feel free to ask — but based on what’s given, here’s the final takeaway:

Final Answer: The table correctly displays the color changes of common indicators in acidic and basic solutions. Use it to determine if a solution is acid or base by matching observed colors.
