is benzoic acid soluble in water, 1.0M NaOH, 1.0M HCl?

Here is a link to the solubility in hot and cold water. Being an acid, it is very soluble in NaOH. From the link on solubility in water you should be able to make an educated guess as to the solubility in cold/hot HCl.

Benzoic acid is partially soluble in water and has limited solubility in cold water. However, it is much more soluble in hot water.

Regarding its solubility in 1.0M NaOH and 1.0M HCl, let's break it down step-by-step:

1. 1.0M NaOH:
Benzoic acid reacts with NaOH to form sodium benzoate, which is highly soluble in water. The reaction is as follows:
C6H5COOH + NaOH → C6H5COONa + H2O

Therefore, benzoic acid is soluble in 1.0M NaOH.

2. 1.0M HCl:
Benzoic acid is not soluble in 1.0M HCl, as HCl is a strong acid and does not undergo the same reaction as NaOH. The presence of HCl does not facilitate the dissolution of benzoic acid.

To summarize:
- Benzoic acid is partially soluble in water, with increased solubility in hot water.
- Benzoic acid is soluble in 1.0M NaOH.
- Benzoic acid is not soluble in 1.0M HCl.

To determine the solubility of benzoic acid (C6H5COOH) in water, 1.0M NaOH (sodium hydroxide), and 1.0M HCl (hydrochloric acid), we need to consider the nature of benzoic acid and its reaction with these substances.

Benzoic acid is a weak acid with a chemical formula C6H5COOH. It has a carboxylic acid group (-COOH), which is responsible for its characteristic acidity. The solubility of benzoic acid in water and other solutions can be determined by understanding its interaction with the surrounding substances.

1. Solubility in Water:
Benzoic acid is moderately soluble in water. At room temperature, it can dissolve up to 3.2 grams of benzoic acid per 100 mL of water. The solubility is due to the formation of hydrogen bonds between the polar water molecules and the polar carboxylic acid group in benzoic acid.

2. Solubility in 1.0M NaOH:
NaOH is a strong base. When benzoic acid reacts with NaOH, it forms its corresponding water-soluble sodium salt, sodium benzoate (C6H5COONa). This reaction occurs due to the neutralization of the acidic carboxylic acid group by the strong basic NaOH. Sodium benzoate is highly soluble in water due to the presence of sodium ions that readily interact with water molecules.

Therefore, benzoic acid is soluble in 1.0M NaOH due to the formation of its water-soluble salt, sodium benzoate.

3. Solubility in 1.0M HCl:
HCl is a strong acid. When benzoic acid reacts with HCl, it forms its corresponding water-soluble salt, benzoic acid chloride (C6H5COCl). This reaction occurs due to the substitution of the hydrogen atom in the -COOH group with the chloride ion from HCl. Benzoic acid chloride is highly soluble in water.

Therefore, benzoic acid is soluble in 1.0M HCl due to the formation of its water-soluble salt, benzoic acid chloride.

In summary:
- Benzoic acid is moderately soluble in water.
- It is soluble in 1.0M NaOH due to the formation of sodium benzoate.
- It is soluble in 1.0M HCl due to the formation of benzoic acid chloride.

its semi soluble.... it only dissolves if heated
