Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
![pH = - log(a_{[H^{+}]})](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%28a_%7B%5BH%5E%7B%2B%7D%5D%7D%29)
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
Answer:
- Rubidium Rb was discovered in 1861
- It was discovered by the German chemist Robert Wilhelm Bunsen and the German physicist Gustav-Robert Kirchoff
Explanation:
Rubidium was discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 while analyzing samples of the mineral lepidolite with a device called a spectroscope. The sample produced a set of deep red spectral lines they had never seen before. Bunsen was eventually able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of refining lithium.

Explanation:
It could them know how it start when it started wats in the infectious disease and why
About 255.3 grams is the answer I believe. I just had a school work packet and had that question on it, and that is the answer that I had put on it I believe.
