Question

Label each of the following as being a strong acid, a weak
acid, or a species with negligible acidity. In each case write the
formula of its conjugate base, and indicate whether the conjugate
base is a strong base, a weak base, or a species with negligible
basicity: (a) HCOOH

Accepted Answer

Hello everyone today we are being given the following question, identify if phosphoric acid is a species with negligible acidity, a weak acid or a strong acid provide its conjugate base and indicate whether it is a species with negligible basis. City a weak base or a strong base. So weak acids to start off with don't completely Iron eyes on the other hand, strong acids are going to completely lionize or separate. And more specifically a strong oxy acid, which is just a strong acid that includes oxygen, has two or more oxygen's than hydrogen. And so we can therefore constitute our phosphoric acid as a week acid. And so when we determine our conjugate base or C. B. This is essentially going to just be taking away a proton. So we're going to end up with a church to P. 04 minus or die hydrogen phosphate. And this is a weak base. Why is it a weak base? Because it is derived from a weak acid. So weak acids directly produce weak bases. And so our final answer is going to be that our phosphoric acid is going to be a weak acid and conjugate base is going to be a weak base due to it being derived from a weak acid. And with that we've answered the question. I hope this helped. And until next time
