According to the stgudents, which solute should they use in their cold pack A. ammonium chloride B. sodium chloride C. calcium chloride D. sodium acetate?
The students should use option D, sodium acetate, in their cold pack. Sodium acetate undergoes an endothermic reaction when dissolved in water, absorbing heat from the surroundings and creating a cooling effect. This makes it an ideal choice for cold packs as it helps maintain a low temperature for longer periods of time compared to the other solutes listed.
What else can I help you with?
When mixed do ammonium chloride and calcium acetate create a precipitate?
Yes, when ammonium chloride reacts with calcium acetate, a precipitate of calcium chloride forms. Ammonium acetate, which is soluble in water, remains in solution.
What is the chemical formula of ammonium acetate NH4C2H3O2?
According to Wikipedia, the formula for ammonium acetate is CH3COONH4 (or C2H4O2.NH3 or C2H7NO2). According to the National Institute of Standards and Technology (NIST) the formula for ammonium acetate is C2H7NO2.
How does the reaction between ammonium chloride and vinegar occur?
When ammonium chloride and vinegar react, they undergo a chemical reaction that produces water, carbon dioxide, and ammonium acetate. This reaction occurs because the ammonium chloride breaks down into ammonia and hydrochloric acid when mixed with the acetic acid in vinegar. The ammonia then reacts with the acetic acid to form ammonium acetate, while carbon dioxide is released as a byproduct.
What are some exaples of salts?
Salts: sodium chloride, barium nitrate, uranyl acetate, plutonium sulfate, ammonium phosphate etc.
Will hexane dissolve ammonium acetate?
No, hexane is a nonpolar solvent and ammonium acetate is a polar compound. Nonpolar solvents like hexane do not dissolve polar compounds like ammonium acetate.
Is Ammonium acetate and Sodium acetate the same thing?
No, Sodium acetate (NaCH3CO2) contains the positive ion of sodium (Na+), a highly reactive metal. It is the product of acetic acid (CH3CO2H) reacting with sodium hydroxide (NaOH). Sodium acetate is mildly basic. Ammonium acetate (NH4CH3CO2H) contains the ammonium ion (NH4+) a polyatomic ion composed of the nonmetal nitrogen and hydrogen. It is the product of ammonia (NH3) reacting with acetic acid. Ammonium acetate is neutral.
What is NH4CH3COO?
NH4CH3COO is the chemical formula for ammonium acetate, a compound commonly used in laboratory applications such as buffers and chemical reactions involving acidic conditions. It is a white crystalline solid that is soluble in water.
Is ammonium acetate a strong or weak electrolyte?
Ammonium acetate is a weak electrolyte. It partially dissociates into ammonium ions and acetate ions in solution, leading to a small concentration of ions being present.
Is ammonium acetate a metal or nonmetal?
Ammonium acetate is a compound that consists of the cation ammonium (NH4+) and the anion acetate (CH3COO-). It is not a metal or nonmetal itself, but it is made up of both a metal (ammonium, which includes a positively charged nitrogen atom) and a nonmetal (acetate, which includes carbon, hydrogen, and oxygen atoms).
Is ammonium acetate covalent or ionic?
Ammonium acetate is an ionic compound. It is formed from the ionic bond between the positively charged NH4+ ion (ammonium) and the negatively charged CH3COO- ion (acetate).
Is ammonium acetate organic or inorganic?
Ammonium acetate is an inorganic compound. It is composed of ammonium ions and acetate ions, which are simple inorganic ions and do not contain carbon-hydrogen bonds typical of organic molecules.
Is ammonium acetate an example of zwitter ion?
Yes, ammonium acetate is an example of a zwitterion. A zwitterion is a molecule that contains both positive and negative charged groups, and in the case of ammonium acetate, it contains a positively charged ammonium group and a negatively charged acetate group.
