- IONIC EQUILIBRIUM
The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium , a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change. For a given set of reaction conditions, the equilibrium constant is independent of the initial analytical concentrations of the reactant and product species in the mixture. Thus, given the initial composition of a system, known equilibrium constant values can be used to determine the composition of the system at equilibrium.

Get Started. Hey, I'm Rajan. I'm determined to make your exam score grow. Lets start the free course. Position yourself for success with a comprehensive curriculum and guidance from seasoned mentors. On the basis of colligative properties of solutions of salts, acids and bases, Arrhenius proposed the theory of ionisation i.
In a chemical reaction , chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactants and products. Such a state is known as dynamic equilibrium. The concept of chemical equilibrium was developed after Berthollet found that some chemical reactions are reversible.

DefineBronsted acid and base Bronsted acid is a substance which gives proton or proton generator or protogenic where as Bronsted base is proton acceptor or takes proton or protophilic. Define Lewis Acid and Lewis Base. Lewis acid is a substance which accepts a lone pair of electron and Lewis base is a substance which donates a lone pair of electron. The condition for Lewis base is it should have at least one lone pair and for the Lewis acid it should have at least an empty orbital to accommadate the pair of electrons received.

In conjunction with lectures on equilibria in electrolytic solutions, students perform a set of laboratory experiments in which they determine both the ionization constant of chloroacetic acid and the solubility of its silver salt.
acceptor(base), and the NH4+ ion acts as a proton donor (acid). Substances such as water, ions such as hydrogen sulphate ion are both Bronsted Lowry acids.
У меня его уже нет, - сказала она виноватым тоном. - Я его продала. ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке. Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы.
- Отключение вручную займет минут тридцать. Фонтейн по-прежнему смотрел на ВР, перебирая в уме остающиеся возможности. - Директор! - взорвался Джабба. - Когда эти стены рухнут, вся планета получит высший уровень допуска к нашим секретам.
Стеклянная панель обдала его дождем осколков. Дверь повернулась и мгновение спустя выкинула его на асфальт. Беккер увидел ждущее такси.
Но затем стала подниматься вторая стена, за ней третья.
