<u>Answer:</u> The volume of concentrated hydrochloric acid solution is 1.73 mL
<u>Explanation:</u>
To calculate the hydrogen ion concentration of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
pH = 1.60
Putting values in above equation, we get:
![1.60=-\log [H^+]](https://tex.z-dn.net/?f=1.60%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-1.60}=0.0251M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-1.60%7D%3D0.0251M)
To calculate the volume of the concentrated solution, we use the equation:
where,
are the molarity and volume of the concentrated HCl solution
are the molarity and volume of diluted HCl solution
We are given:
Putting values in above equation, we get:
Hence, the volume of concentrated hydrochloric acid solution is 1.73 mL
A lunar eclipse can be photographed sometimes when Earth is in between the sun and the Moon.
<h3>Why lunar eclipse occur?</h3>
A lunar eclipse occurs when the Sun, Earth, and Moon align in the same line in which the Moon passes into Earth's shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth's shadow, called the umbra so we can conclude that claim 2 is the right answer about lunar eclipse.
