WRITE A BALANCE EQUATION BETWEEN PHOSPHORIC ACID AND SODIUM HYDROXIDE USING METHYL ORANGE
H3PO4 + 2NaOH ==> Na2HPO4 + 2H2O
To write the balanced equation for the reaction between phosphoric acid (H₃PO₄) and sodium hydroxide (NaOH) using methyl orange as an indicator, let's follow these steps:
Step 1: Write the chemical formula of phosphoric acid and sodium hydroxide.
H₃PO₄ + NaOH
Step 2: Identify the products of the reaction. Phosphoric acid is a triprotic acid, meaning it can donate three protons. Sodium hydroxide is a strong base that can accept one proton. The reaction will result in the formation of water (H₂O) and sodium phosphate (Na₃PO₄).
H₃PO₄ + 3NaOH → Na₃PO₄ + 3H₂O
Step 3: Balance the equation by adjusting the coefficients. In this case, all the coefficients are already balanced, as there are the same number of atoms on both sides of the equation.
H₃PO₄ + 3NaOH → Na₃PO₄ + 3H₂O
This is the balanced equation for the reaction between phosphoric acid and sodium hydroxide using methyl orange as an indicator.
To write a balanced equation between phosphoric acid (H3PO4) and sodium hydroxide (NaOH) using methyl orange as an indicator, we need to consider the reaction between the acid and base to form a salt and water. The equation can be written as follows:
H3PO4 + 3 NaOH -> Na3PO4 + 3 H2O
Here's how you can balance the equation step by step:
Step 1: Write down the unbalanced equation using the reactants (phosphoric acid and sodium hydroxide) and the expected products (sodium phosphate and water).
H3PO4 + NaOH -> Na3PO4 + H2O
Step 2: Balance the phosphorus (P) atoms in the equation by adding a coefficient of 3 in front of Na3PO4.
H3PO4 + NaOH -> 3 Na3PO4 + H2O
Step 3: Balance the hydrogen (H) atoms by adding a coefficient of 3 in front of H2O.
H3PO4 + NaOH -> 3 Na3PO4 + 3 H2O
Step 4: Check if the equation is balanced. Count the number of each type of atom on both sides of the equation. There are:
Left side: 3 hydrogen (H), 1 phosphorus (P), 4 oxygen (O), 1 sodium (Na)
Right side: 3 hydrogen (H), 3 phosphorus (P), 4 oxygen (O), 3 sodium (Na)
All the atoms are now balanced, so the equation is balanced:
H3PO4 + NaOH -> 3 Na3PO4 + 3 H2O
Remember to always double-check the balanced equation to ensure accuracy.
