in Zn we use 3% decolorizer, while in modified 1% h2so4 is used, modified is used for paracite like Cryptosporidium, cyclosporidium and bacterias like nocaddia and actinomyces. also in modified heating isn't done.
Ionic bond will be formed between Zn and Cl. Zinc (Zn) is a metal and Chlorine (Cl) is a non-metal, resulting in the transfer of electrons from Zn to Cl, leading to the formation of an ionic bond.
The skeleton equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl -> ZnCl2 + H2
Unbalanced: HCl + Zn → ZnCl2 + H2Balanced: 2HCl + Zn → ZnCl2 + H2
The balanced equation for the reaction between zinc (Zn) and copper (II) bromide (CuBr2) is: Zn + CuBr2 → ZnBr2 + Cu
The equation is: Zn + 2HNO3 -----> Zn(NO3)2 + H2

The balanced equation for the reaction between zinc (Zn) and bromine (Br2) is: Zn + Br2 -> ZnBr2.
Zn stain, or zinc stain, is a histological staining technique primarily used to highlight the presence of certain microorganisms, such as the spirochetes in syphilis and some fungi. It utilizes zinc salts to enhance the visibility of these organisms under a microscope, allowing for better diagnosis in clinical specimens. The staining process reveals a characteristic coloration that distinguishes the target organisms from surrounding tissue.
The procedure for staining using modified Ziehl-Neelsen (ZN) typically involves the following steps: First, the bacterial smear is fixed onto a slide and then stained with a primary stain, usually carbol fuchsin, which penetrates the mycobacterial cell wall. The slide is then heated gently to facilitate dye uptake, followed by cooling and rinsing with water. Next, the slide is decolorized with an acid-alcohol solution to remove the stain from non-acid-fast organisms, and finally, it is counterstained with methylene blue or another contrasting dye to visualize the background and non-acid-fast cells. The result is that acid-fast bacteria appear red against a blue background.

Bacteria that are stained with the Ziehl-Neelsen (ZN) stain are typically acid-fast bacteria, most notably Mycobacterium tuberculosis, the causative agent of tuberculosis. The ZN stain helps to identify these bacteria due to their unique cell wall structure, which retains the primary dye (carbol fuchsin) even after being exposed to acid-alcohol decolorization. This staining method is crucial for diagnosing tuberculosis and other mycobacterial infections. Other acid-fast bacteria, such as those in the Mycobacterium avium complex, can also be identified using this technique.
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
The balanced chemical equation for the reaction between Zn and O2 is 2 Zn + O2 → 2 ZnO. This equation shows that 2 moles of Zn react with 1 mole of O2 to produce 2 moles of ZnO.
