Question

H3PO4 can be classified as a Select one: O a strong acid O b. weak acid O c. strong base O d. weak base NH3 can be classified as a Select one: a strong acid O b. weak acid O c. strong base O d. weak base HNO3 can be classified as a Select one: a strong acid O b. weak acid O c. strong base O d. weak base

Answer 1

Hope you will like my answer.

as it are HO H₃PO4 and HE weak acid disssociate partially in solution where as and HNO3 is_strong acid since it dissociate completely in solution Similarly NHz is a weak base partially dissociate into solution. as it H+ species is an 3) HNO3 → If acid releases remaining Conjugate ao base. If a base gains Htion, resulting species is Conjugate acid öö 1 H3 PO4 → weak acd. 2) NH3 weak base strong acid 9) Hal → strong 5) HF weak acid 6) Conjugate base of HCO3 = CO32- 7) Conjugate base of H₂O OH 8) Conjugate acid of HGOU H₂ C₂ Ou 9) Conjugate base of NHyt NH3 10). Conjugate base of Halo = clo- strong acid.
