Formic acid ,HCOOH, is a monoprotic acid. circle the acidic hydrogen. Write the formula of the conjugate base after the acidic hydrogen is lost.
the hydrogen attached to the -O- in the OH is the detachable H
Ah, yes, chemistry! Let's break it down. The formula for formic acid, HCOOH, indeed contains an acidic hydrogen. Now, if we lose that feisty hydrogen, the formula of the conjugate base would be COO⁻. It's like formic acid got a little makeover and lost a "plus one" hydrogen! Quite the transformation, I must say.
In the formula "HCOOH", the acidic hydrogen is the hydrogen atom connected to the carboxyl group (-COOH). To identify the acidic hydrogen, we look for the hydrogen atom that is most likely to dissociate as a proton (H+). In this case, the hydrogen atom attached to the oxygen in the carboxyl group is the acidic hydrogen.
When the acidic hydrogen is lost, the resulting species is called the conjugate base. Since the hydrogen is removed, the formula of the conjugate base is obtained by removing the hydrogen and leaving the rest of the molecule intact.
Therefore, after the acidic hydrogen is lost, the formula of the conjugate base of formic acid (HCOOH) is CHOO-.
To identify the acidic hydrogen in formic acid (HCOOH), we need to look for the hydrogen atom that is most likely to dissociate when the acid is dissolved in water.
In the case of formic acid (HCOOH), the hydrogen atom that is attached to the carboxyl group (-COOH) is the acidic hydrogen. This is because the carboxyl group is a strong electron-withdrawing group, making the hydrogen atom more acidic.
After the acidic hydrogen is lost, the resulting species is called the conjugate base. In this case, the formula of the conjugate base of formic acid (HCOOH) can be written as HCOO-. The negative charge is created on the oxygen atom (O-) as it accepts the dissociated hydrogen ion (H+).
So, the formula of the conjugate base of formic acid (HCOOH) is HCOO-.
