Introduction:
In this question, we are given equal volumes of 10% HCl and 10% NaOH solutions. We need to determine the nature of the resultant solution when these two solutions are mixed. We are also given the density relationship between pure NaOH and pure HCl.
Understanding the problem:
To solve this problem, we need to understand the concept of acidic, basic, and neutral solutions. If a solution has a pH less than 7, it is considered acidic. If the pH is greater than 7, it is considered basic. And if the pH is exactly 7, it is considered neutral.
Solution:
Let's break down the solution into steps:
Step 1: Determine the nature of the individual solutions:
- A 10% HCl solution is acidic because HCl is a strong acid.
- A 10% NaOH solution is basic because NaOH is a strong base.
Step 2: Determine the pH of the individual solutions:
- Since both solutions have the same concentration, the pH of the HCl solution and the NaOH solution will be the same.
Step 3: Determine the pH of the resultant solution:
- When an acid and a base react, they neutralize each other. The resulting solution will have a pH close to 7, making it neutral.
- However, in this question, we are given that the density of pure NaOH is 1.5 times that of pure HCl. This indicates that NaOH is more concentrated than HCl.
- As a result, the excess NaOH will not completely neutralize the HCl. There will be an excess of OH- ions in the solution, making it basic.
- Therefore, the resultant solution will be basic.
Conclusion:
The resultant solution, when equal volumes of 10% HCl and 10% NaOH solutions are mixed, will be basic. The excess NaOH in the solution will make it basic.
