Is water (H2O) classified as a strong or weak acid or base? Explain. You have an acid that dissociates partially in solution. Is this a strong or weak acid? Explain. Is H3PO4 a strong acid, strong base, weak acid, or weak base? Classify the acid and base as either a s...
The strength of an acid and a base is dependent on how stable the conjugate is. The more stable the conjugate is, the stronger acid or base is. For instance, the conjugate base of HCl is {eq}Cl^- {/eq}. Since {eq}Cl^- {/eq} is a stable anion, then it is...

A salt that is formed from a neutralization reaction can exhibit acidic or basic properties. Aqueous solutions of these salts have non-neutral pH values at 298 K. This is due to the ionization of a weak acid or base that results in the formation of hydroni...
• Acidity or Basicity of H3PO4 So, is H3PO4 an acid or base?H3PO4 is a weak acid because it does not dissociate completely in its aqueous solution or water. The strength of acidity of the compound depends on the number of hydrogen ions in the solution after its dissociation and ...
