SN in water

[yasmine299]

Could someone please confirm if the water turns really cold after mixing sn in it?

 

[Kikoo]

Why would it lol

 

[yasmine299]

I really don't know, the cup turned really cold after I mixed sn, so just confirming if I have the right chemical.
It says this about nitrate.
Anybody would know if the same happens for nitrite?

Interesting, how much water and SN ?

 

[yasmine299]

5gm of SN in approximately 20 ml.

SN = sodium nitrite = NaNO2 !

how much water and SN

I meant how much did they test to turn the water cold.

I was only trying to test my sn for purity, so as per the guide ( I followed vizzy's) I took some water (approximately 20 ml) out of cup 1 and mixed it with 5gm of sn.

SN = sodium nitrite = NaNO2 !

Yes I understand, that is why I asked the question here, google answered for Nitrate, was wondering if similar reaction would happen for Nitrite?

Wow this also happened to me. I mixed 20g SN with 50ml water and it was really cold idk if this is a problem

Yes and nobody has mentioned anything like this before, I was really confused. Did you test your sn for purity?

Yes I did an aquarium test and the SN was good

I've seen a couple of goodbye threads by people who used the same source as me and they never came back to this site.

After consulting some chemists and ChatGPT I can confirm that sodium nitrite indeed does turn cold after dissolving it in water. Here is what ChatGPT said:

does sodium nitrite turn cold after dissolving it in water?

"Yes, dissolving sodium nitrite in water can result in a decrease in temperature, which is a phenomenon known as the "temperature drop" or "cold dissolving." This occurs because the dissolution of certain salts in water is an endothermic process, meaning it absorbs heat from the surroundings, including the water itself, leading to a lowering of the overall temperature.
Sodium nitrite is one of the salts that can exhibit this behavior. When the solid sodium nitrite is added to water, it requires energy to break the bonds between the sodium and nitrite ions in the solid crystal structure. This energy is taken from the surrounding water, causing a decrease in temperature.
It's important to note that not all salts exhibit this effect when dissolved in water. Some salts, like common table salt (sodium chloride), dissolve exothermically, meaning they release heat and can cause the temperature of the solution to rise.
The extent of the temperature change depends on factors such as the amount of sodium nitrite being dissolved and the initial temperature of the water. In scientific terms, the temperature change can be quantified using the enthalpy of dissolution, which represents the heat absorbed or released during the dissolution process."
