Answer:
An isotope is an element that has a different amount of neutrons than its standard atomic mass. ... Subtract the number of protons from the atomic mass. This is the number of neutrons that the regular version of the atom has. If the number of neutrons in the given atom is different, than it is an isotope.
Explanation:
Answer:
The pH of pure water at this temperature is 6.88.
Explanation:
Ionization constant of water = 

Water will dissociate into equal amount of hydronium and hydroxide ions
![[H_3O^+] = [OH^-]= x](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%20%3D%20%5BOH%5E-%5D%3D%20x)
![K_w=[H_3O^+]\times [OH^-]](https://tex.z-dn.net/?f=K_w%3D%5BH_3O%5E%2B%5D%5Ctimes%20%5BOH%5E-%5D)
![K_w=1.7 x 10^{-14}=[H_3O^+]\times [OH^-]](https://tex.z-dn.net/?f=K_w%3D1.7%20x%2010%5E%7B-14%7D%3D%5BH_3O%5E%2B%5D%5Ctimes%20%5BOH%5E-%5D)


The pH of the solution is a negative logarithm of hydronium ions concentration.
The pH of pure water at this temperature:
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
