Sulfuric acid is needed in a lead storage battery. A 25.00-mL sample of "battery acid" taken from a functioning battery requires 53.7 mL of 4.552 M NaOH for complete neutralization. What is the molarity of the battery acid?

Q: Expert Answer

Interpretation Introduction Interpretation: The molarity of battery acid should be calculated. Concept introduction: Number of moles is equal to the ratio of given mass to the molar mass. The mathematical expression is given by: Number of moles = given mass molar mass Molarity is defined as the ratio of number of moles of solute to the volume of the solution in liters. The mathematical expression is given by: Molarity = moles of solute volume of solution in liters A solution of salt of metal when reacts with other solution to give products, the formula which is used to find the volume of either solution is given by: M 1 V 1 =M 2 V 2 Where, M 1 and M 2 are molarity of the solution V 1 and V 2 are volume of the solution Explanation The reaction between sulfuric acid and sodium hydroxide is: H 2 SO 4 +2NaOH → Na 2 SO 4 + 2 H 2 O Now, molarity of sodium hydroxide is 4.552 M Volume of sodium hydroxide is 53.7 mL Volume of battery acid is 25.00 mL Therefore, Molarity = moles of solute volume of solution in liters Number of moles = Molarity × Volume of solution in liters Convert given volume that is 53.7 mL in liters Since, 1 mL = 0.001 L Thus, 53.7 mL × 1 L 1000 mL = 0.0537 L Number of moles = 4.552 moles/L × 0.0537 L= 0 .244 mole Number of moles of sodium hydroxide = 0

Interpretation Introduction

Interpretation:

The molarity of battery acid should be calculated.

Concept introduction:

Number of moles is equal to the ratio of given mass to the molar mass.

The mathematical expression is given by:

Number of moles = given massmolar mass

Molarity is defined as the ratio of number of moles of solute to the volume of the solution in liters.

The mathematical expression is given by:

Molarity = moles of solute volume of solution in liters

A solution of salt of metal when reacts with other solution to give products, the formula which is used to find the volume of either solution is given by:

M1V1=M2V2

Where, M₁ and M₂ are molarity of the solution

V₁ and V₂ are volume of the solution

Explanation of Solution

The reaction between sulfuric acid and sodium hydroxide is:

H2SO4+2NaOH→Na2SO4+2H2O

Now, molarity of sodium hydroxide is 4.552 M

Volume of sodium hydroxide is 53.7 mL

Volume of battery acid is 25.00 mL

Therefore,

Molarity =moles of solute volume of solution in liters

Number of moles = Molarity × Volume of solution in liters

Convert given volume that is 53.7 mL in liters

Since, 1 mL = 0.001 L

Thus, 53.7 mL×1 L1000 mL=0.0537 L

Number of moles = 4.552 moles/L × 0.0537 L= 0.244 mole

Number of moles of sodium hydroxide = 0
