Give the conjugate base of the following Brønsted–Lowry acids: (i) HCOOH, (ii) HPO42-.

Video transcript

Hello everyone today. We are being asked to provide the conjugate base of the acids, oxalate and acetic acid. So the first thing you want to do is you want to recall what a conjugate base is. So a conjugate base is simply the compound formed when an acid loses a proton. So loses a proton or H. Plus. So simply we just take each of our compounds here. We'll start with the oxalate first and we will subtract a proton from this, giving us our regular last eight and then we're going to take our acetic acid CH three COOH. We're going to subtract a proton and this is going to give us acetate. And so these two our final answers. I hope this helped and until next time.
