Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
When sodium hydroxide is mixed with water, a chemical reaction takes place where the sodium hydroxide dissociates into its ions, Na+ and OH-. This is a physical change.
How does sodium oxide and water make sodium hydroxide?
When sodium oxide reacts with water, it undergoes a chemical reaction to form sodium hydroxide. This reaction involves the hydration of sodium oxide, which results in the formation of sodium hydroxide as a product. The chemical equation for this reaction is: Na2O + H2O → 2NaOH.
Is iron chloride and sodium hydroxide a physical or chemical change?
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
What is the chemical equation of ethanoic acid reacting with sodium hydroxide?
The chemical equation for the reaction between ethanoic acid (acetic acid) and sodium hydroxide is: CH3COOH + NaOH → CH3COONa + H2O This reaction is a neutralization reaction that forms sodium acetate and water.
Can i replace potassium dichromate to sodium dichromate?
Yes, sodium dichromate can generally be used as a substitute for potassium dichromate in certain chemical reactions. However, it is important to consider the specific reaction conditions and the reactivity of each compound before making the substitution. It is recommended to consult a chemical reference or expert before making the switch.
What is the balanced chemical equation of the reaction of mixing sodium dichromate and nitric acid?
Sodium dichromate has the chemical formula of Na2Cr2O7. The reaction with HNO3 is balanced as 2 HNO3 + Na2Cr2O7 = H2Cr2O7 + 2 NaNO3.

What is sodium oxide combines with water to make sodium hydroxide?
When sodium oxide reacts with water, it forms sodium hydroxide by the following chemical equation: Na2O + H2O -> 2NaOH. This reaction releases heat and is highly exothermic. Sodium hydroxide is a strong base commonly used in industries such as water treatment, soap making, and chemical production.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride Adding more sodium hydroxide to the reaction causes it to speed up If you add more of a reactant such as sodium hydroxide?
Adding more sodium hydroxide will increase the concentration of the reactant in the reaction, leading to more successful collisions between particles and thus speeding up the reaction. This happens because there are more particles available to react with hydrogen chloride, resulting in a higher reaction rate.
Reaction between sodium hydroxide and methanol?
When sodium hydroxide reacts with methanol, a neutralization reaction occurs, forming sodium methoxide and water. The balanced chemical equation for this reaction is: CH3OH + NaOH → CH3ONa + H2O
What causes the reaction between glucose solution and sodium hydroxide?
The reaction between glucose solution and sodium hydroxide is a chemical reaction that involves the hydrolysis of glucose molecules by the strong base (sodium hydroxide). This reaction results in the formation of sodium gluconate and water. The hydroxide ions from the sodium hydroxide cleave the glycosidic bonds in glucose molecules, leading to the breakdown of glucose into simpler compounds.
What chemical compound has been used up in the reaction between sodium hydroxide and hcl?
In the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl), the chemical compound that is used up is sodium hydroxide (NaOH), as it reacts with hydrochloric acid to form water (H2O) and sodium chloride (NaCl).
Is Reaction of hydrochloric acid with sodium hydroxide a chemical change?
Yes, the reaction of hydrochloric acid with sodium hydroxide is a chemical change. It forms water and sodium chloride, which are different substances with new chemical properties compared to the reactants.
