Suppose you have 557 mL of 0.0300 M HCl, and you want to make up a solution of HCl that has a pH of 1.751. What is the maximum volume (in liters) that you can make of this solution?

Interpretation Introduction

Interpretation:

The maximum volume that you can make of the given solution has to be  determined.

Concept introduction:

pH is an logarithmic expression to express a solution is acidic, basic or neutral.  pH scale lies values between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

We have to calculate the concentration of hydronium ion by using the following formula.

[H3O+] = 10-pH

The pH is equal to pH = -log10c

Where, c is hydrogen ion concentration in moles per liter.

To determine the volume of the given solution, use the following formula

M1V1 = M2V2

Explanation

The given pH value is 1.751

Now, let’s determine the concentration of hydronium ion as follows.

[H3O+] = 10-pH = 10-1.751= 0.017742M

Finally, to determine the volume of the given solution, use the above said formula as follows
