Is Na2CO3 an acid or base or salt? Strong or Weak - Sodium ...

Sodium carbonate neither acidic nor basic, it is salt made up of a strong base and weak acid. So, when Na 2 CO 3 dissolved in water, it will raise the pH of the aqueous solution by lowering the amount of hydrogen (H +) ions, as it contains the stronger base (NaOH) which dominates the solution. Therefore, with the presence of more OH – ions in ...

alkalinity

Strongly buffered liquids are difficult to shift pH. Water in the natural environment has a mild buffering capacity and may be easily disturbed by the entry of small amounts of acid or alkaline substances. Laundry detergents are, in the main, alkaline, that is their pH in water is above 7, maybe as high as 11 (strongly alkaline).
