Chemical Composition and Equivalents of Phosphoric Acid
How many equivalents of phosphoric acid are contained in 300 ml of 4.00 M phosphoric acid?
Phosphoric acid (H₃PO₄) consists of three hydrogen atoms, one phosphorus atom, and four oxygen atoms. It is commonly used in various industries and applications due to its acidic properties and versatility. What is the number of equivalents of phosphoric acid in this solution?
Answer:
In 300 ml of 4.00 M phosphoric acid, there are 3.60 equivalents of phosphoric acid.
Phosphoric acid (H₃PO₄) is a chemical compound that plays a significant role in various chemical processes and industries. It has three acidic hydrogen atoms, meaning it can donate three protons, which correspond to one equivalent each.
To calculate the number of equivalents in 300 ml of 4.00 M phosphoric acid, we first need to determine the number of moles of phosphoric acid in the solution. Using the formula for molarity (M), we find that there are 1.20 moles of phosphoric acid in 300 ml of 4.00 M solution. Since each mole of phosphoric acid corresponds to three equivalents, the total number of equivalents in 300 ml of 4.00 M phosphoric acid is 3.60 equivalents.
Therefore, in 300 ml of 4.00 M phosphoric acid, there are 3.60 equivalents of phosphoric acid, making it a versatile and crucial compound in various industries.
