By BYJU'S Exam Prep

Updated on: September 25th, 2023

The balanced equation is 2Na + 2H2O → NaOH + H2. Balance is necessary for every chemical equation. This necessitates that each sort of atom is present in precisely the same quantity on both sides of the arrow. This is because all chemical reactions result in the conservation of mass. Determine how many oxygen and hydrogen atoms are on either side of the arrow. Both the reactants and the products include two hydrogen atoms.

In this post, we will go through the step-by-step solution for the question “Balance: Na+H2O→NaOH+H2”

Na + H2O → NaOH + H2, Balance the Equation.

The purpose of balancing chemical equations is to make both sides of the reaction, the reactants, and the products, equal in the number of atoms per element. This is because matter cannot be generated or destroyed, in accordance with the fundamental law of conservation of mass. The steps to Balance the Na + H2O → NaOH + H2 equation are as follows:

Step 1: Na, O, and H are the three components that contribute to the reaction. Simply keep track of the number of times an element appears on both the left and right sides of the equation.

Element Reactant (LHS) Product (RHS)

  • Sodium 11
  • Oxygen 11
  • Hydrogen 23

The reason this equation is unbalanced is that the number of hydrogen atoms on each side is not equal.

Step 2: Now that the equation is balanced, multiplying NaOH and H2O by 2 will result in a total of four hydrogen atoms on both sides of the equation. Next, multiplying Na by 2 will balance the sodium atoms.

Element Reactant (LHS) Product (RHS)

  • Sodium 22
  • Oxygen 22
  • Hydrogen 44

Hence, the balanced equation is 2Na + 2H2O → 2NaOH + H2

Uses of Sodium

Additionally, the uses of Sodium are as follows:

  • Additionally, it is utilized in soaps, the purification of molten metals, sodium vapor lamps, and enhancing the structure of some alloys.
  • Sodium is a component of sodium chloride, a key substance present in the environment that supports life.
  • Making esters and producing organic molecules both depend on sodium.
  • Glassmaking requires solid sodium carbonate.


Balance: Na + H2O → NaOH + H2

The balanced equation is 2Na + 2H2O → NaOH + H2. Sodium hydroxide is a by-product of chlorine production. In its pure form, it is a crystalline solid and naturally colorless. This compound is water-soluble and contains hydroxide anions and sodium cations.
