2021年12月30日 · A neutralisation reaction is a reaction during which an acid reacts with a base to form a salt and water only. I understand the part : A neutralisation reaction is a reaction during which an acid reacts with a base. since, given that the acid is an H+ donor and the base and H+ acceptor, they will react to form water and bring the pH back to 7.

2020年11月4日 · The reaction $\ce{CaO + SiO2 -> CaSiO3}$ is considered a neutralization reaction despite not producing water, because both reactants are reacting with water to produce a hydroxide ($\ce{Ca(OH)2}$ and an acid $\ce{H2SiO3}$.

2017年9月30日 · Of course, a base reaction can be considered essentially the reverse, meaning that the acid constant typically given is actually $\mathrm pK_\mathrm a (\ce{HB+})$ rather than anything directly corresponding to the free base. If we now take the reaction of a (weak) acid and a (weak) base, we get equation $(3)$ and the equilibrium constant as ...

You are right in that the reaction is $\mathrm{H}^+ + \mathrm{OH}^- \rightarrow \mathrm{H_2O}$, but recognise that bonds are formed in this reaction. Bond formation releases energy (and similarly bond breakage is endothermic), and thus neutralisation reactions are exothermic.

2015年3月15日 · $\begingroup$ I tried again to understand the question hahah and i hope this time I'll help.It's not that any of these reactions will be complete and it depends on the strength of either reactant.Neutralisation between an acid and a base either of which or both are weak will be a reversible reaction which means that it is not complete, on the other hand strong acid a …

2021年9月11日 · $\begingroup$ The statement that "neutralization is the reaction of an acid and a base producing a salt plus water" is a concept developed in the 19th century. The reaction of $\ce{CaO + SiO2}$ is not really a neutralization. It is a synthesis. $\endgroup$ –

2018年7月18日 · One can think of it as simply because of electrostatic attraction. Basically, an acid produces $\ce{H+}$ ions in water while a base produces $\ce{OH-}$ ions in water. So when you mix an acid and a base (e.g. sulfuric acid and sodium hydroxide) in a beaker, you get a solution containing $\ce{H+}$ and $\ce{OH-}$ ions.

2016年8月22日 · In this neutralization reaction, Fe(OH)3 forms a dirty green ppt. which is insoluble in water.This demonstrates one point as to why neutralization reactions are irreversible. There maybe other points as well, such as specific temperature and pressure conditions,etc.

2019年7月20日 · The neutralization of a strong acid with a strong base then is always the same reaction: $$\ce{H+(aq) + OH-(aq) -> H2O(l)}$$ We can calculate the enthalpy of reaction from the enthalpies of formation at a temperature of $\pu{25 ^\circ C}$ .

2024年8月19日 · I think that the reaction between ammonia and $\ce{H3O+}$ is not appreciably reversible and thus drives the total reaction to "completion." To be honest, this is an oversimplification, but for the sake of clarity: Assume that: $$\ce{NH3 + …
