Answer 2

Answer:

• table salt is considered a salt

•      Soap is categorized as base

•      Toothpaste is a base

•       Baking soda is a base

•       Water is neutral

•       Curd is an acid

•       Milk is a base

•       Alum is a metal

•       Iron is a metal

•       Sulfur is a non-metal

•       Washing powder is a base

Explanation:

• Acid:- it is a substance that has particular chemical properties like turning litmus red, neutralizing alkalis, and dissolving some metals, generally a corrosive or sour-tasting liquid.

• Base:- it is a substance that tastes bitter in water solution is slippery to touch, changes the color of indicators (e.g., turns red litmus paper blue), when it reacts with acids it forms salts, and builds certain chemical reactions (base catalysis).

• Metal:- it is an element that produces positive ions and has metallic bonds. There are large numbers of elements on the periodic table that are metals. They are characterized by high electrical and thermal conductivity and so on by malleability, ductility, and high reflectivity of light e.g., of metal elements, including iron, copper, silver, mercury, lead, aluminum, gold, platinum, zinc, nickel, and tin.

• Non-metals:-it is an element that forms negative ions by accepting or gaining electrons. Usually, they have 4, 5, 6, or 7 electrons in their outermost shell. they lack all the metallic attributes. A good insulator of heat and electricity. Mostly gases and sometimes liquid are found. At room temperatures Carbon, sulfur, and phosphorus these types of elements are solid in state.

• salt:- it is a chemical compound formed of an anionic group of positively charged cations and negatively charged anions, with no net electric charge. An example is table salt, with positively charged sodium ions and negatively charged chloride ions, produced by the reaction of an acid with a base and the reaction of an acid and a base is called a neutralization reaction.

Hence,

• table salt is considered a salt

•      Soap is categorized as base

•      Toothpaste is a base

•       Baking soda is a base

•       Water is neutral

•       Curd is an acid

•       Milk is a base

•       Alum is a metal

•       Iron is a metal

•       Sulfur is a non-metal

•       Washing powder is a base
