The salt formed by the combination of hydrochloric acid and sodium hydroxide solution is called sodium chloride. This is the salt that you use in food. It is a neutral salt. Seawater contains many salts dissolved in it. Sodium chloride is separated from these salts. Deposits of solid salt are also found in several parts …
Nature provides neutralisation optionsNettle is a herbaceous plant which grows in the wild. Its leaves have stinging hair,which cause painful stings when touched accidentally. This is due to the methanoic acid secreted by them. A traditional remedy is rubbing the area with the leaf of the dock plant, which often grows beside the nettle in …
Acids in other planetsThe atmosphere of venus is made up of thick white and yellowish clouds ofsulphuric acid.
Are plants and animals pH sensitive ? Our body works within the pH range of 7.0 to 7.8. Living organisms can survive only in a narrow range of pH change. When pH of rain water is less than 5.6, it is called acid rain. When acid rain flows into the rivers, it lowers the pH …
A scale for measuring hydrogen ion concentration in a solution, called pH scale has been developed. The p in pH stands for ‘potenz’ in German, meaning power. pH Definition Negative logarithm of the H+ or , H3O+ ion concentration. pH = – log [H+] On the pH scale we can measure pH generally from 0 …
A neutralisation reaction is a chemical process in which an acid and a base combine to produce salt and water as the end products. H+ ions and OH– ions combine to form water during a neutralisation reaction. Acid-base neutralisation is the most common type of neutralisation reaction. As we have identified that all acids generate …
This experiment suggests that hydrogen ions in HCl are produced in the presence of water. The separation of H+ion from HCl molecules cannot occur in the absence of water. HCl + H2O → H3O+ + Cl–Hydrogen ions cannot exist alone, but they exist after combining with water molecules. Thus hydrogen ions must always be shown …
What Happens to an Acid or a Base in a Water Solution? Read More »
All acids have similar chemical properties. that all acids generate hydrogen gas on reacting with metals, so hydrogen seems to be common to all acids. All compounds containing hydrogen are acidic. Because they are both electrolytes, acids and bases are effective electrical conductors. Ions are produced in water solutions by both bases and acids. While …

Non-metal oxides are acidic in nature. When a base reacts with non-metal oxide, both neutralize and produce corresponding salt and water .Base + Non metal oxide ⟶ Salt + WaterExample: 2 Ca(OH)2 + CO2 ⟶ CaCO3 + H2O Base Acid The reaction between carbon dioxide and calcium hydroxide (lime water) . Calcium hydroxide, which is …
