what is the percent dissociation of acetic acid in a 0.1M solution if the [H3O+] is 1*10-3 mole/liter?相关知识点: 试题来源: 解析 翻译:0.1 M的乙酸溶液,H+浓度是1*10-3 mol/L,求醋酸的电离度. pH=3,水的电离可以忽略,那么电离出的氢离子全部来自乙酸. 电离度=已经电离的乙酸/全部乙酸=氢...
A weak acid ionizes only to a small extent in water. Determine whether the statement is true or false: the %-dissociation of a weak acid increases with increasing initial acid concentration True or false? If a strong acid such as HCl is diluted...
Percent Ionization: The percent ionization tells us that if we start with 100 molecules of a weak acid, then how many molecules are ionized to form protons and conjugate base. Answer and Explanation:1 Given Data The acid dissociation constant {...
This results in a small dissociation constant of Ka<1 and its corresponding expression relating the molarity values of the acid, hydrogen ion and conjugate base species. A weak acid is often assumed to have negligible dissociation at equilibrium. This...
In which B denotes the base. A weak base in an aqueous solution does not fully ionize and has a relatively low dissociation degree. Hence, a large proportion of the weak base molecules is undissociated. Answer and Explanation:1 Note that in this ques...
Answer and Explanation: Given: Acid dissociation constant, {eq}K_{a} = 7.95\times 10^{-3} {/eq} The concentration of solution = 0.140 M. The percent ionization of this...Become a member and unlock all Study Answers Start today. T...
Ionization can take place by the loss of an electron if a collision should occur, with any kind of particle. It is also possible for ionization to take place via radioactive decay. Answer and Explanation: The percent ionization of a 0.175...
