Question

Test tube A + geranium petals \rightarrow Color changes to Bluish
Test tube B + Chinese hibuscus \rightarrow Color changes to brown
Determine A and B?

• A. A is acid B is base
• B. A is base B is acid
• C. Both A and B are acids
• D. Both A and B are bases

Answer 1

The correct option is D Both A and B are bases

Geranium petals contain the anthocyanin pelasgonin, which changes from orange red in an $acidic$ $solution$ to blue in $basic$ $solution$.

Thus, text tube A has a base.

Also, chinese hibuscus changes from red in $acidic$ $solution$ to brown in a $basic$ $solution$.

Thus, test tube B is also a base.
