The OH group bonding with the carbonyl group has a pKa around 5, and the OH group connected ortho of the carbonyl group has a pKa around 10.
Added correction:
Salicylic acid is a monoprotic, not a diprotic acid in water.
From wikipedia table value: pKa 2.97
It is slightly basic. Behaves almost completely neutral.
Salicylic acid dissociates in water to form a carboxylic acid group, making it more acidic compared to acetylsalicylic acid which has an ester group that is less acidic. The presence of the -OH group in salicylic acid contributes to its higher acidity compared to the -OR group in acetylsalicylic acid.
Salicylic acid is a solid at room temperature.
Salicylic acid, like any other acid, would be dissolved in water.
Salicylic acid is a precursor to aspirin, which is a derivative of salicylic acid. When salicylic acid is acetylated, it becomes aspirin. Aspirin is a common medication used for pain relief and reducing inflammation.

Most acne washes have salicylic acid or benzoyl peroxide. Salicylic Acid has 7 carbons, 6 Hydrogens, and 3 Oxygens. Salicylic Acid is also called 2-Hydroxybenzoic Acid. Benzoyl Peroxide has 14 Carbons, 10 Hydrogens, and 4 Oxygens. Benzoyl Peroxide is also called dibenzoyl peroxide. I hope this is what your looking for.
It is not understood by what you mean by ' reverse' . CuSO4 (Copper sulphate) is an entirely different chemical to salicylic acid. CuSO4 is a blue soluble inorganic solid salt. Salicylic Acid ( 2-hydroxybenzoic acid) is a white crystalline mildly soluble and mildly acidic organic acid .

You can find Salicylic Acid in a lot of Acne medications.

Salicylic acid acetyl is made by reacting salicylic acid with acetic anhydride in the presence of an acid catalyst, such as sulfuric acid, to form acetylsalicylic acid. This reaction causes the hydroxyl group (-OH) of salicylic acid to be acetylated, resulting in acetylsalicylic acid, commonly known as aspirin.
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic acid.
No, salicylic acid is not soluble in citrate solutions. Salicylic acid is an organic compound that is generally insoluble in water-based solutions like citrate.
Salicylic acid is also known as 2-Hydroxybenzoic acid. The literature Ka value is 2x10 to the negative 14th power. Which makes salicylic acid a somewhat strong acid.
