These reactions describe the equilibrium dissociation or ionization (ion formation) of the acid molecule. The equilibrium constant equation that quantifies these types of reaction have the following form: {eq}K_a = \dfrac{[A^-][H_3O^+]}{[HA]} {/eq}View...

Equilibrium: When an acid dissociates, equilibrium is reached with its conjugate base. In the case of strong acids, the equilibrium strongly favors the product or is to the right of a chemical equation. The conjugate base of a strong acid is much weaker than water as a base. Solvent: In ...
A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, making more hydrogen ions available to bond with base ions in the water. A strong base also...
An example reaction is the dissociation of ethanoic acid in water to produce hydroxonium cations and ethanoate anions:一个例子反应是乙酸在水中解离产生氢氧基阳离子和乙酸根阴离子: CH3COOH + H2O ⇆ H3O++ CH3COO- Note the reaction arrow in the chemical equation points in both directions. Only ...
the more polar O-H bond=more acidic *Buffers consists of a weak acid and its conjugate base *Henderson-Hasselbalch equation always use moles acid and strong base base and strong acid For acid-base titrations Strong acid + Strong base pH = 7 Ksp # of product 2 x2 3 4x3 4 27x4 5 ...
a teacher is good at chemistry, this is no indication of their ability to teach you or your child. The dissociated molecules are in equilibrium with undissociated molecules. No matter how much water you remove, that will be true. What happens when you mix a strong acid and a strong base...
Is this a strong or weak acid? Explain. Is HI a strong acid, strong base, weak acid, or weak base? Is NH3 a strong acid, strong base, weak acid, or weak base? Weak acids: a. are always more soluble than strong acids. b. have a higher degree of dissociation than do s...
From the perspective of acid-base reactions, the sodium cations are of no importance in the solution. In fact, sodium hydroxide is used as a way to deliver hydroxide anions to the solution. You can thus say that every mole of sodium hydroxide dissolved in soluti...
