WebFeb 9, 2024 · [HCOOH] + [HCOO –] = Ca. For the general case of an acid HA, we can write a mass balance equation Ca = [HA] + [A – ] (1-16) which reminds us the "A" part of the acid must always be somewhere! Similarly, for a base B we can write Cb = [B] + [HB + ] (1-17) Degree of dissociation varies inversely with the concentration

Formate esters have the formula HCOOR (alternative way of writing formula ROC(O)H or RO2CH). Many form spontaneously when alcohols dissolve in formic acid. The most important formate ester is methyl formate, which is produced as an intermediate en route to formic acid. Methanol and carbon monoxide react in the presence of a strong base, such as sodium methoxide: WebJan 30, 2024 · If the acid or base conducts electricity strongly, it is a strong acid or base. If the acid or base conducts electricity weakly, it is a weak acid or base.

"WebIt is a buffer because it contains both the weak acid and its salt. Hence, it acts to keep the hydronium ion concentration (and the pH) almost constant by the addition of either a small amount of a strong acid or a strong base. If we add a base such as sodium hydroxide, the hydroxide ions react with the few hydronium ions present. " - Is hcoo- a strong base
