The potassium reacts with the water to form potassium hydroxide and hydrogen gas. The reaction is very exothermic, and the hydrogen explodes during the reaction. THIS IS A VERY DANGEROUS REACTION! DO NOT ATTEMPT IT ON YOUR OWN!
it becomes warm
It gets numb.
Yes, you can put dry ice in salt water. It will bubble furiously and cool down the salt water.
When that happens it uses up all the oxygen and replaces it with co2 (carbon dioxide) and water and that what makes the sucking affect :)
If you boil it, the water will boil and the dye will not, leaving you with dye.
Sodium chloride is easily dissolved.
The potassium catches on fire and then explodes. Seriously. Don't try it.
Potassium chloride is melted at 770 oC.
when particles of KCl are put in water, they dissolve because KCl being a polar ionic compound, its ions separate and in aqueous solutions, water molecules surround these ions with the partially positive hydrogen ions closer to the chloride ions and the partially negative oxide ion towards the potassium ion but the electron cloud is bigger on the side of the chloride ion since it's more electronegative and the attraction between the hydrogen and the chlorine and between oxygen and potassium becomes stronger than that between potassium and chlorine hence the two ions [potassium and chloride] are pulled apart forming ions in the solution
Sodium chloride is dissolved and dissociated in water.
Potassium metal will react violently with water to form KOH and hydrogen gas. Due to the heat released by the reaction - the hydrogen gas will ignite. So: placing potassium in water will cause a fire!
Yes, you make salt water with salt and water.
Potassium chloride is the answer as it would've neutralised the other liquid and the salt is potassium nitrate and therefore is named after like the salt and neutralisation put in.
Add warm water to dissolve the KBr which is very soluble. This would become the aqueous layer and would be more dense and thus at the bottom. Add them to a sep funnel and decant. Evaporate the water off and you have the KBr. The remaining fluid in the sep funnel is npahthalene
When you put magnesium chloride (MgCl2) in water, it dissociates into magnesium ions (Mg2+) and chloride ions (Cl-). This process releases energy in the form of heat, as it is an exothermic reaction. The resulting solution of magnesium chloride in water can conduct electricity due to the presence of free ions.
Preheated aluminum will burn when introduced to chloride
When copper chloride is put into water, it starts dissociating. The molecule of copper chloride breaks up to give a cuprous ion(Cu2+) and 2 Chloride ions(Cl-). The water molecules weakly dissociate to give hydrogen ions(H+) and Hydroxyl ions(OH-). The oppositely charged ions interact and form a weak bond known as hydrogen bond. This interaction results in the copper chloride dissolving in the water.
