Assess the accuracy of the following statements, in the order presented. (1) Bicarbonate (HCO3-) is amphoteric

Answer

true; false

Explanation

The Bicarbonate Ion HCO3- Is Amphoteric;
This is because bicarbonate can Act As Either An Acid Or A Base In Water:
As an acid: HCO3- + H2O → CO32- + H3O+ (acid)
As a base: HCO2- + H2O → H2CO3 + OH- (base)
An acid with low pH is stronger compared to an acid with higher pH.
Since pH is inversely related to the concentration of Hydrogen ions, strong acids have higher concentration of hydrogen ions and hence a low pH.
For example, carbonic acid is a weak acid and has higher pH near 7, while sulphuric acid is a strong acid with low pH near 1.
