Answer: The pH of phenol solution is 4.7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Given : ![[H_3O^+]=1.8\times 10^{-5}M](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D1.8%5Ctimes%2010%5E%7B-5%7DM)
Putting in the values we get
![pH=-\log[1.8\times 10^{-5}M]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B1.8%5Ctimes%2010%5E%7B-5%7DM%5D)
Thus pH of phenol solution is 4.7
Answer:
Explanation:
Protons have a positive charge, with a mass of 1 amu.
Neutrons have no charge, also with a mass of 1 amu.
Electrons have a negative charge, with a mass of 1 amu.
This is why when you're calculating the mass of an element or isotope, we only count the number of protons and neutrons.
A warm front is also defined as the transition zone where a warmer air mass is replacing a cooler air mass
Dew point: The point at which air saturated with water vapor produces condensation which forms dew.
A. The electron moves from a lower to a higher energy orbital
Scientists used the calculated density to determine that Mercury holds a large metallic core. Radar images taken from Earth revealed that the core is molten liquid, rather than solid. Mercury's core has more iron than any other planet in the solar system.
