Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.
Bases turn pH paper blue or purple in color.
Litmus paper is a substance that changes color in the presence of acids or bases. Acids turn litmus paper red, while bases turn it blue. By observing the color change, you can identify whether a substance is acidic or basic.
In acids, lotus stems turn pink or red due to the presence of anthocyanins. In bases, lotus stems turn green or yellow as the anthocyanins change their structure.
Acid turns it in red, while base will turn it blue.
