How is dry ice formed when sodium acetate is added to water?
Dry ice is not formed in this instance.Dry ice is solid carbon dioxide. The phenomenon involving sodium acetate is colloquially called hot ice. Simply adding sodium acetate to water will not produce this. You need to create a supersaturated solution. You add sodium acetate to water untill it cannot dissolve any more, and then cool the solution. Now you have an unstable solution that has more dissolved sodium acetate than it could normally hold. If it is disturbed, the sodium acetate will sponaneously crystallize.
What materials would you need to make hot ice?
sodium acetate water pan
How much vinegar is needed for making sodium acetate?
The chemical reaction for the preparation of sodium acetate is: CH3COOH + NaHCO3 → CH3COONa + H2O + CO2 Now you need to calculate the quantities from the molecular masses; it is not complicate.
How is sodium acetate made and why is it?
You add either sodium hydroxide, sodium carbonate or sodium bicarbonate to acetic acid, and receive a solution of sodium acetate in water. Driving off the water will give you sodium acetate crystals. Hundreds of tons a year are made of this because it has hundreds of uses, so most people who need some just buy it. In a school science lab the safe way to make it is to mix baking soda with vinegar then boil off the water with a hot plate. If you have a factory you make this out of sodium hydroxide and glacial acetic acid, then pour the sodium acetate solution into a pond to evaporate, like they do to get the salt out of seawater.
How does one make hot ice from scratch?
You will need to start by acquiring some sodium acetate trihydrate (order online or take from an "instant" warming pad). Place about 1 cup into a pan and add just enough water to dissolve it (don't add too much). Heat this mixture almost to the point of boiling. Stir constantly and keep adding sodium acetate until no more will dissolve. Pour the liquid into a glass (don't let any undissolved sodium acetate get into the glass). Place the glass in a freezer for 30-60 minutes. Poke the liquid with a small amount of solid sodium acetate on the end of a toothpick. If you hold your hands near the "ice" you will feel heat radiating.
What is the neutralization equation of hc5h7o5co2 and nahco3?
nahco3 + ch3cooh --> co2 + CH3COONa + h2oNote: it is CH3COONa (sodium acetate) and not na2co3(sodium carbonate) as stated in the question above
How much salt do you need to add to water to solidify it?
You cannot solidify water using salt. As you add salt to water, the concentration in the water increases until the water is saturate. After that any more salt you add will simply not dissolve. It is possible to create a supersaturated solution by adding the salt to warm water and then cooling it. Disturbing the water will cause some salt to precipitate and sink the to bottom. You can, however, solidify water using sodium acetate. First you add enough sodium acetate to hot water that the concentration is greater than 1.2 g/ml. Then allow the solution to cool. After it is cooled, drop in a single grain of sodium acetate.
Can you use sodium chloride flush on a dog wound?
Not recommended; ask a veterinary doctor.
Do guinea pigs need sodium?
yes they do need sodium
Do plants need sodium to grow?
No, plants do not need sodium to grow. They need protein to grow.
Why do people need hot ice?
The hot ice as in an hot-pack is used to store heat that won't be lost when it's in an cold enviroment. The particle that causes the ice to be hot(Sodium acetate: NaCH3COO) is also used in food as an preservative and an acidity(pH) regulator.
How do you make DCA or di chloride acetate safe for human consumption in medicine?
It is impossible to make it safely for (self)-medical uses. And by the way: DCA means DiChloroAcetic acid which is neither a chloride (salt of eg. sodium, not of 'di') nor an acetate (salt of acetic acid) but the an acid itself (CHCl2COOH).The problem with producing this acid compound is you need Chlorine (Cl2) gas which is a very toxic and dangerous chemical.
