Question

Write in the chart which molecule is the acid,base, conjugate base,conjugate acid from the equation and watching the H+ movement

1 H2CO3 + H2O--- H3O+ +HCO3-
2 H3PO4 + H2O--- H2PO- +H3O+
3. HCO3- + H2O---H2CO3 +OH-
4 HNO3 +H2O---NO3- +H3O+​

Answer 1

When H2O acts as a base, it gains one H, which forms its conjugate acid, H30. ... Write the formula for the conjugate base for each of the following acids: a. ... H3PO4(aq) + H2O(l) 7 H2PO4 (aq) + H3O+(aq) ... CO32-(aq) + H2O(1) 2 HCO3 (aq) + OH(aq) ... balanced equation for the reaction of the ammonium ion with water.
