Is H3PO4 a weak base?
H3PO4 is a weak acid but its salt (Na3Po4) with strong base NaOH is neutral Explain it. 0 like 0 dislike.
Is H3PO4 a weak electrolyte?
HC 2 H 3 O 2 (acetic acid), H 2 CO 3 (carbonic acid), NH 3 (ammonia), and H 3 PO 4 (phosphoric acid) are all examples of weak electrolytes. Weak acids and weak bases are weak electrolytes. In contrast, strong acids, strong bases, and salts are strong electrolytes. Note a salt may have low solubility in water, yet still be a strong electrolyte because the amount that does dissolve completely ionizes in water.
Is H3PO4 an acid or a base?
H3PO4 is a weak acid, so it does not fully ionise in water. Hence, H2PO4- can be treated as a weak, base as it is the conjugate base of a weak acid. HOWEVER! for examples of water testing to test for a phosphate ion , we need to have the phosphate ion on its own in solution.
Is H3PO4 a strong or weak acid?
This is a misconception! H3PO4 is not considered as a weak acid. Its pKa is in the range of HSO4! It’s far (about 40 times) stronger than formic acid !
