What is the pH of sodium benzoate?
Sodium benzoate is a salt derived from benzoic acid, which is weakly acidic. The pH of a solution containing sodium benzoate would depend on the concentration of the solution, but typically it would be acidic with a pH below 7.
What is sodium benzoate made of?
Sodium benzoate is made from benzoic acid, which is a naturally occurring compound found in some fruits and spices. It is then combined with sodium hydroxide to form sodium benzoate, which is commonly used as a food preservative.
Why does benzoic acid precipitate out when the aqueous layer is acidified with HCl?
You're starting with something like sodium benzoate (depends on what base you used for the extraction step), which contains sodium ions (Na+) and benzoate ions (C6H5COO-). Ionic compounds like that tend to be soluble in water. When you add H+, you protonate the benzoate ion to make benzoic acid (C6H5COOH), which is a neutral molecule, and hardly soluble in water at all... so it precipitates.
What are constituent elements of sodium benzoate?
Sodium benzoate is composed of sodium ions (Na+) and benzoate ions (C7H5O2-). When sodium benzoate is dissolved in water, it dissociates into these ions. Sodium benzoate is primarily used as a preservative in food and beverages.
What is the common name for sodium benzoate?
Another common name doesn't exist; the code of sodium benzoate is E211.

What mass of sodium benzoate should be added to 160.0 mL of a 0.15 mL benzoic acid solution in order get a buffer with a pH of 4.30?
To create a buffer with a pH of 4.30, you need to use the Henderson-Hasselbalch equation and the pKa of benzoic acid to calculate the ratio of benzoate ion to benzoic acid. From there, you can determine the moles of sodium benzoate needed and then convert it to grams. Make sure to consider the volume change when adding the sodium benzoate to the solution.

When you lower the pH of a solution containing aqueous sodium benzoate a precipitate eventually forms What will happen if you then raise the pH after the reaction by adding aqueous NaOH?
When you raise the pH by adding aqueous NaOH after a precipitate forms in a solution of aqueous sodium benzoate due to a pH decrease, the precipitate likely dissolves. This is because sodium benzoate is the conjugate base of benzoic acid, so at higher pH levels, it remains in solution. The sodium benzoate will revert back to being fully soluble in its aqueous form.
Does sodium benzoate contain iodine?
No, sodium benzoate does not contain iodine. Sodium benzoate is a sodium salt of benzoic acid and is often used as a preservative in food and beverages. Iodine is a different element that is not found in sodium benzoate.
Is sodium benzoate gluten free?
sodium benzoate glutin free
What is the sodium amount in 100mg of sodium benzoate?
15,95 mg of sodium in 100 mg sodium benzoate
What would you see when acidified silver nitrate solution is added to a solution of Low sodium salt?
When acidified silver nitrate solution is added to a solution of low sodium salt, it would form a white precipitate of silver chloride. This is due to the chloride ions in the low sodium salt reacting with the silver ions in the silver nitrate solution to form silver chloride, which is insoluble in water.
What is the chemical symbol for sodium benzoate?
Sodium benzoate has the formula C6H5COO-Na+
