Acids and Bases

أحماض وقواعد برونستيد-لوري
أحماض وقواعد برونستيد-لوري
The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their ability to ...
قوى الحمض/القاعدة وثوابت التفكّك
قوى الحمض/القاعدة وثوابت التفكّك
The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, ...
الماء: حمض وقاعدة برونستيد-لوري
الماء: حمض وقاعدة برونستيد-لوري
The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, ...
مقياس درجة الحموضة
مقياس درجة الحموضة
Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as ...
القوى النسبية لأزواج حمض-قاعدة المترافقة
القوى النسبية لأزواج حمض-قاعدة المترافقة
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate acid-base ...
حمض قوي ومحاليل أساسية
حمض قوي ومحاليل أساسية
A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial ...
المحاليل الحامضية الضعيفة
المحاليل الحامضية الضعيفة
Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of ...
المحاليل القاعدية الضعيفة
المحاليل القاعدية الضعيفة
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and ...
مخاليط الأحماض
مخاليط الأحماض
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two ...
الأيونات كأحماض وقواعد
الأيونات كأحماض وقواعد
Salts with Acidic Ions Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization ...
تحديد الرقم الهيدروجيني (pH) لمحاليل الملح
تحديد الرقم الهيدروجيني (pH) لمحاليل الملح
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations ...
أحماض بوليبروتيك
أحماض بوليبروتيك
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ...
قوة الحمض والبنية الجزيئية
قوة الحمض والبنية الجزيئية
Binary Acids and Bases In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A ...
أحماض وقواعد لويس
أحماض وقواعد لويس
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to ...
