Because iodine is nonpolar, a nonpolar substance like ethanol would dissolve it. Iodine is insoluble in polar substances like water.
The solvent is ethanol (mostly) and water in tincture of iodine.
The added compound is potassium iodide (KI).
Hexane or chloroform
yes it is
The microbiocidal action of Iodine is due to the active form, I2, which is polarized by water and like all halogens (chlorine, fluorine, bromine, etc.), acts as an extremely potent oxidizer. Activated iodine (I2) reacts in electrophilic reactions with enzymes of the respiratory chain as well as with amino acids located in cell membrane and cell wall proteins. The well-balanced tertiary structure necessary for maintaining the respiratory chain as well as cell integrity is destroyed and the microorganism is irreversibly damaged.
As per the exact chemistry, I am unsure, but basically the iodine acts to "set in" the stain by reacting the dye (crystal violet) from the previous step with the peptidoglycan layer, forming a layer which is now insoluble in the following step where the layer is washed with EtOH. If the cell is Gram (-), the iodine doesn't do much and the dye is washed away.
The solute is the salt.The water is the solvent.The water acts as a solvent to the solute of salt. It forms a solution when the salt has fully dissolved into the water.Get it?
Bromine is the only element acts as a liquid in the room temperature. The upper elements in the same group are gases. Iodine is a solid that can undergo sublimation in room temperature.
Yes, but not at the same time. Such substances are called amphoteric. Their acidic or basic character depends on the substance they are reacting with.A good example of an amphoteric substance is water.When water reacts with a substance more basic than itself (like ammonia), it acts as an acid.H-OH + NH3 --> NH4+ + OH-When water reacts with a substance more acidic than itself (like hydrochloric acid), it acts as a base.HCl + H2O --> H3O+ + Cl-
the one which is more in amount is the solvent
Water
The water in a solution is called the solvent
In coffee, solutes refer to the substances that dissolve in water, such as soluble coffee compounds, sugars, and acids. Water acts as the solvent, which is the substance in which solutes dissolve. So, in coffee, water is the solvent and the solutes include the coffee compounds, sugars, and acids.
You can dissolve things into it.
