Pretty sure A is the correct answer
The peaks at 3300 cm-1 and 2200 cm-1 are due to terminal alkyne group (triple bond between two carbons) and triple bonded C-H stretching
So
The answer is : terminal alkyne
Another peak near 3430 cm-1 must be due to an -OH group
so the answer is : alcohol
Ga, 31 electrons/ protons, 39 neutrons
Answer: The pH of solution is 10.
The pOH of the solution is 4.
Explanation:
pH is the negative logarithm of concentration of hydrogen ion.
As given concentration of acidic solution is
. Therefore, pH of the solution is calculated as follows.
![pH = -log [H^{+}]\\= -log (1.00 \times 10^{-10})\\= 10](https://tex.z-dn.net/?f=pH%20%3D%20-log%20%5BH%5E%7B%2B%7D%5D%5C%5C%3D%20-log%20%281.00%20%5Ctimes%2010%5E%7B-10%7D%29%5C%5C%3D%2010)
The relation between pH and pOH is as follows.
pH + pOH = 14
pOH = 14 - pH
= 14 - 10
= 4
Thus, we an conclude that pH of solution is 10 and pOH of the solution is 4.
