The strong acids are hydrochloric acid盐酸, nitric acid硝酸, sulfuric acid硫酸, hydrobromic acid氢溴酸, hydroiodic acid氢酸, perchloric acid上氯酸, and chloric acid氯酸. The only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). While technically a weak ...
更新1: In this formular: eg of weak base: NH3 + H2O --- NH3+ + OH- Where did the another H+ went to?strong acid donates H+ and weak acid doesn't refuse to donate H+ weak acid also donates H+. no matter strong acid or weak acid when a substance in solu...
analyte, weak acid titrant, strong base reaction during titration HC2 H3 O2 NaOH HC2 H3 O2 + NaOH ↔ NaC2 H3 O2 The extent of dissociation can also be described by dissociation constants symbolized as a Ka (for acids) and Kb (for bases). Since the Ka or Kb can be a very small or...
H2SO4- sulfuric acid (HSO4-is a weak acid) HBr - hydrobromic acid HI - hydroiodic acid HClO4- perchloric acid HClO3- chloric acid Examples of ionization reactions include: HCl → H++ Cl- HNO3→ H++ NO3- Read More List of the Strong Acids and Key Facts ...
Strong vs Weak AcidA strong acid is a solution containing H3O+ ions that fully dissociate while a weak acid is a solution where the H3O+ ions only dissociates partially. The most popular strong acids are hydrochloric acid (HCl), sulfuric acid, and nitric acid, while the most common weak ...
The strong and weak acids are decided based on the dissociation ability of that acid. If an acid dissociates fully, it is considered a strong acid,... Learn more about this topic: Weak Acids | Definition, List & Examples from Chapter 28/ Lesson 13 ...
A linear titration equation for determination of weak acids in the presence of small amounts of a strong acid is derived. The titration is performed potentiometrically. Equal volumes of the titrant are added stepwisely. More satisfactory results are obtained from the determination of an extremely ...
This weak acid-strong base type charge-mosaic membrane exhibited quite high ion selectivity in comparison with previous strong acid-strong base type charge-mosaic membranes. 展开 DOI: 10.1016/S0376-7388(00)85098-X 被引量: 30 年份: 1989
Although the use of strong and weak acids can be found in the literature, there is still a clear lack of reliable comparisons between them. This paper presents a comparison of the results obtained for a real lead contaminated soil treated by EKR enhanced with nitric or with acetic acid. The...
