Is Sodium hydroxide dissolving in water a chemical or physical change?
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.
What type of change is sodium hydroxide dissolving into water?
It is a physical change because no new substances are formed during the process of dissolving. Sodium hydroxide dissociates into its ions in water, but the chemical composition of the sodium hydroxide remains the same.
What is the ionic equation of sodium carbonate?
nickel sulfate + sodium carbonate -> sodium sulfate + nickel carbonate
What happens when you put sodium nitrate in 30c?
Sodium nitrate would dissolve in water at 30°C to form a solution. It increases the conductivity of the solution and may react with other ions in the water. Sodium nitrate is commonly used as a food preservative and fertilizer.
What is the balenced equation of dissolving sodium in water produces sodium oxide and hydrogen?
Sodium reacts with water to form sodium hydroxide and hydrogen. The balanced equation is 2Na + 2H2O --> 2NaOH + H2.
What is the net ionic equation for sodium hydroxide dissolve?
Dissolving is not a chemical reaction; any chemical equation.
What is the chemical equation of this reaction Solid sodium chloride dissolves in water.?
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
What causes difference in water density?
the presence of minerals such as sodium cholride,magnesium etc causes the difference in ocean water ....
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
What is word equation for sodium with water?
The word equation for sodium reacting with water is: sodium + water → sodium hydroxide + hydrogen gas.
What is the process of sodium chloride dissolving in water?
dissociation
What causes differences in density of ocean water?
the presence of minerals such as sodium cholride,magnesium etc causes the difference in ocean water ....
Where is salt water made?
Salt water is obtained by dissolving sodium chloride in water.
Is the dissolving of sodium chloride in water endothermic or exothermic reaction?
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Is Sodium hydroxide dissolving in water a chemical or physical change?
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
What is the word equation for making sodium sulphate and water?
Sodium + Sulphate + Water = Sodium Sulphate + Water
