i.1. Chemical Dynamics: Reactions in our daily substances

We use a large number of substances in our daily life such as lemon, curd, sugar, salt, tamarind etc. Some of these substances taste sour, some taste bitter, some taste sweet and some taste salty. Some of these substances change. Thus, A chemical reaction is described by a chemical equation, an expression that gives the identities and quantities of the substances involved in a reaction, emphasizing the significance of Chemical Dynamics in understanding these transformations.

Caution

Acids and bases are corrosive in nature. These are also irritating and harmful to skin.

Chemical Dynamics of Acids: Sour Side of Nature

  • Meaning: Dynamics of Acidic Nature: The word acid comes from the ‘Latin’ word acere – means sour. 
    • Examples: Curd, lemon juice, orange juice and vinegar taste sour because they contain acids. 
    • Nature: The chemical nature of such substances is acidic. 

Bases: Bitter Essence and Soapy Touch in Chemical Dynamics 

  • Meaning: Substances which are bitter in taste and feel soapy on touching are known as bases. 
  • Example: Baking Soda.
  • Nature: The nature of such substances is said to be basic.

Indicators  in Chemical Dynamics:

  • Meaning: Indicators for Acid-Base Reactions: Substances used to test whether a substance is acidic or basic are known as indicators. 
  • Observed Changes: The indicators change their colour when added to a solution containing an acidic or a basic substance.
    • Indicators can be both natural and synthetic.

Acids in other planets: The atmosphere of venus is made up of thick white and yellowish clouds of sulphuric acid.
