Why is HBrO3 a stronger acid than H2SeO3 ? Decide whether A is more or less acidic than B, and explain your choice. Explain why the -OH in acetic acid is acidic (will lower the pH in water) while the -OH in ethyl alcohol is not. ...
When hydrochloric acid dissolves in water, what ions are formed? a. only H+ b. H and Cl c. OH- and Cl- d. only Cl- e. H+ and Cl- Which one of the following salts is obtained by the reaction of a weak acid with a strong base? (a) MgCl_2. (b) NH_4F. (c) LiCl...
Which of the following is not a strong acid? (a) HNO3 (b) H2SO4 (c) H2S (d) HClO4. Strong Acids: The strength of acids can be described by looking at how much they can dissociate in solution. Strong acids dissociate completely in solution while weak ...
The greater or more complete the ionization, the stronger the acid. For instance, HCl is a strong acid. A solution of HCl consists of mostly hydrogen and chloride ions. Weak acids are acids that do not completely ionize. Answer and Explanation: The correct choi...
Of the following, which is the strongest acid? (a) {eq}\displaystyle \rm HIO {/eq} (b) {eq}\displaystyle \rm HIO_2 {/eq} (c) {eq}\displaystyle \rm HIO_3 {/eq} (d) {eq}\displaystyle \rm HIO_4 {/eq} Defining Oxyacid: Oxyacids are those in which ...
The strength of an acid depends on its acid dissociation constant, ka value. Higher the ka more easily it can give up a proton H+ and so stronger it is. Stronger acids have ka>1 and weak acids have ka<1 are called weak acids. Weak acids are par...
a. HClO b. HClO4 c. HClO2 d. HClO3 e. none of the above Basic Organic Chemistry and its Compounds A weak base does not completely dissociate or they partially dissociate into water. Hypochlorous acid is a weak base which dissociate into ClO−. ...
c. Lewis acid d. Lewis base Bronsted-Lowry and Lewis Acid-Base: The Bronsted-Lowry and Lewis definition of acid-base uses two different concepts: acceptance/donation of unshared pair of electrons and protons. For example, nitric acid is a...
Conjugate Base of a Weak Acid in a SolutionA conjugate base will ionize in water to form its corresponding weak acid and hydroxide ions. The pH can be calculated from the Kb value of the conjugate base.Answer and Explanation: We are going to calculate a solution of 0.13 M CN...
When a weak base is titrated using a strong acid, the pH of the medium decreases gradually with the addition of the strong acid. The pH of the medium decreases sharply at the close proximity of the equivalence point. The pH at the equivalence po...
