do weak acids donate protons?
8433
By contrast, however, a weak acid, being less willing to donate its proton, will only partially dissociate in solution.

any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) ... solutions of weak acids have a low concentration of H+. 3. the molecular form of the weak acid does exist in solution.

A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. ... The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid. At the same concentration, weak acids have a higher pH value than strong acids.

So it should be no surprise to find that very weak bases such as halide ions (I-, Br-, Cl-) water (OH2), and sulfonates such as p-toluenesulfonate (OTs) and methanesulfonate (OMs) are excellent leaving groups. These are the conjugate bases of strong acids.

Because in general all acids with the carboxylic group (COOH) are weak or at least not really strong. Just look at formic acid (HCOOH) with a pKa of 3,77 or acetic acid (CH3COOH) with a pKa of 4,75.

The acid part is circled; it is the H atom in that part that can be donated as aspirin acts as a Brønsted-Lowry acid. Because it is not given in Table 12.2 “Strong Acids and Bases”, acetylsalicylic acid is a weak acid.

Acids have the tendency to lose H+ atoms, which are also referred to as "protons" because of their positive charge. Another term used for acids is electron acceptor. Bases, on the other hand, are referred to as proton acceptors or electron donors.

If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). ... They simply do not ionize completely whereas a strong acid or base does.

Unlike strong acids/bases, weak acids and weak bases do not completely dissociate (separate into ions) at equilibrium in water, so calculating the pH of these solutions requires consideration of a unique ionization constant and equilibrium concentrations.

A weak acid alone is not a buffer, because there aren't appreciable quantities of the conjugate base. Buffers cannot be made from a strong acid (or strong base) and its conjugate. This is because they ionize completely! It is important to be able to recognize buffer solutions!

Examples of weak bases include ammonia, NH3, and diethylamine, (CH3CH2)2NH. Most weak bases are anions of weak acids. Weak bases do not furnish OH- ions by dissociation. Instead, they react with water to generate OH- ions.

Strong acids react completely with water to produce H3O+(aq) (the hydronium ion), whereas weak acids dissociate only partially in water. Conversely, strong bases react completely with water to produce the hydroxide ion, whereas weak bases react only partially with water to form hydroxide ions.
1445074
Strong acids dissociate fully in water to produce the maximum number of H + ions. ... Weak acids, such as ethanoic acid (CH 3COOH), do not fully dissociate. In fact, about only one per cent of ethanoic acid molecules split up to form H + ions and CH 3COO – ions at any one time.
372627
Strong acids and bases are less stable than weak acids and bases because they are more reactive. ... A weak base is resistive to being protonated because it is stable. A strong base is going to accept a proton easily because it's less stable.

The weakest acid has the smallest Ka. In this problem that would be (D) HCN. In general, the more positive the pKa is, the weaker the acid.
348816
There are six common strong acids: HClO4, HI, HBr, HCl, H2SO4, and HNO3. The conjugate base of a strong acid is neutral. In contrast to strong acids, weak acids ionize only partially in aqueous solution.

A salt formed from reaction of a weak base and a strong acid should give an acidic solution. For example, NH4Cl is formed from the reaction of NH3, a weak base, and HCl, a strong acid. The chloride ion will not hydrolyze. ... A salt formed from reaction of a strong base and a weak acid should give a basic solution.
