Answer:
1.The neutral substances that are the most well known are: water, table salt, sugar solution and cooking oil. Cooking oil is a neutral substance. We have learnt about three classes of substances: acids, bases and neutral substances.
2.A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.
3.In many acid-base reactions, the resulting product is water along and a salt. If hydrochloric acid (HCL) and the base sodium hydroxide (NaOH) are combined, the product is H2O (water) and NaCl (sodium chloride, a table salt).
4.Salts can be acidic, basic, or neutral. Acidic salts are formed when a strong acid reacts with a weak base. Basic salts are formed when a strong base reacts with a weak acid. When a strong acid reacts with a strong base, neutral salts are formed.
