In this example, that conjugate base is the nitrate. Always confused between the conjugate acid base concept. 0 0. prashant Soni. 1973. And for CO3^2- it should be obvious not to pick H2O as its conjugate pair. HNO3 is an acid, and it releases a proton into the water as a result of the chemical reaction. 1. here H2CO3 and HCO3- are conjugate acid-base pair as are H2O and OH-b) HCl + H 2 PO 4-----> Cl - + H 3 PO 4. a. H3O+/H2O. What are acids and bases? b. HNO2/NO2-becoz conjugate acid have more H than its conjugate base. HCO3-1/ CO3-2. Acids are proton( H+) donor. In both instances, mass and charge are conserved. H2CO3/HCO3-1. 9 years ago. HCl transfers a proton (H+ ion) to H 2 PO 4- and form Cl - and H 3 PO 4, now Cl - can accept a proton donated by H 3 PO 4 .so the above equation is; HCl + H 2 PO 4- -----> Cl - + H 3 PO 4. acid base base acid. H2O is the conjugate acid of the base OH1-. here H2CO3 and HCO3- are conjugate acid-base pair as are H2O and OH- b) HCl + H 2 PO 4 - <------------> Cl - + H 3 PO 4 HCl transfers a proton (H+ ion) to H 2 PO 4 - and form Cl - and H 3 PO 4 , now Cl - can accept a proton donated by H 3 PO 4 .so the above equation is; The conjugate base of H 2 CO 3 is HCO 3-.. To determine the conjugate base, remove a proton (H +) from the acid.The formula will have one less hydrogen... See full answer below. H2SO4 /HSO4-1. Trust me this is going to be your last struggle. HSO4-1 /SO-2. Example: Write the formula of the conjugate base for the following compound: HSO4- Example: Write the formula of the conjugate acid for the following compound: V2O52- Problem : HI(aq) + H2O(l) ⇌ H3O(aq) + I-(aq)Identify each as either a: Bronsted-Lowry acid, Bronsted-Lowry base, conjugate acid, or conjugate … Raman P. Lv 6. Source(s): I am M. Sc. the conjugate base pair is H2CO3 HCO31- is the conjugate acid of the base CO32-. To conjugate an acid, it is necessary to place it in water to create a chemical reaction with the H2O molecules. So far I worked it out to be: Ag2CO3(s) 2Ag^+ + CO3^(2-) H2CO3(aq) + H2O(l) H3O^(1+) science (a) Find the concentration of H+, HCO3 - and CO3 2-, in a 0.01M solution of carbonic acid if the pH of this is 4.18. 9 years ago (c) is a real conjugate acid/base pair. H-Cl / Cl-1. [Arrhenius concept] 2. If we add a proton to water we get #H_3O^+#, the hydronium ion, which is an hypothetical species but is nevertheless useful for acid/base calculations.. 0 0.
