Question

Non-metal used to make an antiseptic solution called tincture.

Answer 1

Hint: To determine the answer to this question we should know about non-metals, uses of non-metals, antiseptics, and tincture. The plant extract dissolved in ethanol is known as tincture. The ethanol has antimicrobial properties. The tincture can also be prepared from the element having low volatility such as non-metals like elements of group-seventeen.

Complete answer:The wounds and cuts open the living tissue to the environment. The antiseptics are the creams or solutions that are applied to wounds and cuts to prevent the wounds and cuts from bacterial infection.The tincture is an antiseptic. The solvent in tincture is ethanol whose concentration can be varied. The tincture of iodine contains two-seven percent elemental iodine, along with potassium or sodium iodide dissolved in water and ethanol solvent.It is a purple colour solution which is applied on wounds and cuts to heal them.Iodine is a p-block element. The p-block, each group contains metal, non-metal and metalloids. In –block iodine belongs to the group-seventeen. Only the group-seventeen contains all the nonmetals that are fluorine, chlorine, bromine and iodine. Iodine has low volatility.So, the non-metal used to make an antiseptic solution called tincture is iodine.

Therefore, iodine is the correct answer.

Note:Tincture of iodine or iodine solution is used for the sterilization of the body. Iodine is moderately toxic, so tincture of iodine is only for external use, so it is a primary disinfectant. Tincture of iodine is also available in the form of an alcohol-free water-based solution. It can also be used in a very minute amount to disinfect the drinking water and to sanitize the surface of fruits and vegetables.
