Neutral red is a kind of weak alkaline pH indicator. Its color change range is pH 6.4-8.0 (from red to yellow). In a neutral or slightly alkaline environment, the living cells of plants can absorb a large amount of neutral red and excrete it to the vacuoles. Because the vacuoles are generally acidic, the neutral red entering the vacuoles will dissociate a large number of cations and present cherry red. In this case, the protoplasm and cell wall are generally not stained; the cell fluid of dead cells cannot be maintained due to the degeneration and coagulation of protoplasm On the contrary, the cation of neutral red binds to the protoplasm and nucleus with certain negative charge and makes the protoplasm and nucleus stain.
Acid base indicator, pH 6.8 (red) ~ 8.0 (yellow); alkalinity indicator of water, nitrite and urine; hydrolysis indicator of fat in histochemistry; Nissl staining of nerve cells; in vitro staining of blood with Jianna green; Photometric Determination of iodine ion; preparation of neutral red test paper.
