The extract of red rose turns the liquid X to green. What will the nature of liquid X be? Class 7
The extract of red rose turns the liquid X to green. What will the nature of liquid X be? What will happen when excess of amla juice is added to liquid X? Class 7
Answer:
Red rose extract acts as an indicator, which turns red in acidic solutions and green in basic solutions. If the extract of red rose turns the liquid X to green, it indicates that liquid X is basic.
When excess amla juice is added to liquid X, it will neutralise the base. The green colour of the liquid will turn to red, because the solution becomes acidic due to the excess addition of amla juice (which is acidic).
