What else can I help you with?
Who will melt earlier benzoic acid or sodium chloride?
sodium chloride melt earlier because it has low freezing point
What acid is formed from sodium benzoate and ammonium chloride?
They are nonreactive towards each other in aqueous solutions but separately in acidic medium sodium benzoate forms the benzoic acid and ammonium chloride forms ammonia in basic medium.
What is the chemical formula of the mixed sodium chloride and benzoic acid and Congo red?
Jbv
What 2 substances will be formed when hydrochloric acid reacts with sodium hydroxide?
HCl + NaOH = H2O + NaCl Or, water and table salt--which will dissolve in water. Benzoic acid, C6H5COOH, will not be formed; neither of the two starting chemicals contains carbon, and benzoic acid contains a lot of it. - - - - - Benzoic acid and sodium chloride
Is sodium benzoate soluble in sodium chloride?
Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)
What equation is this HCl(aq) plus C6H5COONa(aq) -- and gt C6H5COOH(s) plus NaCl(aq)?
There can be no such reaction. Perhaps you meant HCl(aq) + C6H5COONa to get C6H5COOH plus NaCl. That would be converting the sodium salt of benzoic acid (sodium benzoate) into benzoic acid and sodium chloride by using hydrochloric acid.
How is the completeness of separation of the benzoic acid crystals from sodium chloride known with the addition of AgNO3 solution?
Silver Nitrate solution produces a white precipitate in the presence of chloride ion. The equation is AgNO3 + Cl- ----> AgCl(s) . So if benzoic acid is completely free of sodium chloride there will be no white precipitate. You can go a stage further by weighing an aliquot of benzoic acid crystals and titrating with a known strength silver nitrate solution. By calculation you can then find just exactly how much sodium chloride is left contaminating the benzoic acid.
Reaction of benzoic acid with sodium bicarbonate?
When benzoic acid reacts with sodium bicarbonate, it results in the formation of sodium benzoate, carbon dioxide gas, and water. This reaction is an example of an acid-base reaction where the benzoic acid (acid) reacts with sodium bicarbonate (base) to form sodium benzoate (salt) and carbon dioxide gas.
What is the derivative of benzoic acid?
The derivative of benzoic acid is sodium benzoate, which is often used as a preservative in food and beverages due to its antimicrobial properties. Sodium benzoate is the sodium salt of benzoic acid and is more soluble in water than benzoic acid itself.
Why does sodium benzoate react with hydrochloric acid?
Sodium benzoate is a salt of a weak acid (benzoic acid). In water, sodium benzoate hydrolyses to form a strong base (sodium hydroxide) and benzoinc acid. This is an equilibrium reaction. Benzoic acid being a weak acid is only partially ionized in water whilst sodium hydroxide is fully ionoized. The resultant solution is therefore alkaline since the concentration of hydroxyl ions is greater than the concentration of hydrogen ions. The addittion of hydrochloric acid results in an acid base reaction formating a salt (sodium chloride). Since the addition of hydrochloric acid removes the sodium hydroxide, it forces the equilibrium to the right forming more benzoic acid which is precipitated.
Why does sodium bicarbonate deprotonate benzoic acid but not 2-naphthol?
When you deprotonate benzoic acid with 2-napthonal, carbonic acid is produced. With sodium bicarbonate, it splits into sodium and bicarbonate ions.
What is the product of benzoic acid reacting with NH2?
benzoic acid + Sodium Hydroxide ==> water + sodium benzoate
