Answer:
Coefficient = 1.58
Exponent = - 5
Explanation:
pH = 2.95
Molar concentration = 0.0796M
Ka = [H+]^2 / [HA]
Ka = [H+]^2 / 0.0796
Therefore ;
[H+] = 10^-2.95
[H+] = 0.0011220 = 1.122 × 10^-3
Ka = [H+] / molar concentration
Ka = [1.122 × 10^-3]^2 / 0.0796
Ka = (1.258884 × 10^-6) / 0.0796
Ka = 15.815 × 10^-6
Ka = 1.58 × 10^-5
Coefficient = 1.58
Exponent = - 5
Can you tell us what you mean and post the questions ?
Answer:
p-Nitro acetanilide. 2-Naphthol aniline dye.
A. Gold,lead,glass,brick, and steel
b. 8 because they are all over 1.0 density level
c. ice and paraffin (maybe wood but that is not a liquid)<span />
PH of a solution is negative log of its hydrogen ion concentration. Mathematically it can be written as:
![pH = - log[ H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%5B%20H%5E%7B%2B%7D%5D%20)
For the said problem pH will be:
![pH = -log [ 1.659 * 10^{-9} ] \\ pH=-(log[1.659]+log[10^{-9}]) \\ pH=-log[1.659]+9log[10] \\ pH=-0.22+9=8.78](https://tex.z-dn.net/?f=pH%20%3D%20-log%20%5B%201.659%20%2A%20%2010%5E%7B-9%7D%20%5D%20%5C%5C%20pH%3D-%28log%5B1.659%5D%2Blog%5B10%5E%7B-9%7D%5D%29%20%5C%5C%20pH%3D-log%5B1.659%5D%2B9log%5B10%5D%20%5C%5C%20pH%3D-0.22%2B9%3D8.78)
Thus the pH of solution will be 8.78.
