Gain enough kinetic energy to get past each other. Ad you heat up a substance, the temperature increases as does the kinetic energy of the particles. At a point the temperature of the substance will stop increasing. The energy is now being used to increase the potential and move the particles further apart.
The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high ![\rm [H]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5D)
will have:
Option B. A low ![\rm [OH ^{-}]](https://tex.z-dn.net/?f=%5Crm%20%5BOH%20%5E%7B-%7D%5D)
and a high 
This characteristic can be explained as:
- The concentrations of
![\rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D)
and are inversely dependent on each other so when the concentration of raises then the concentration of drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
![\rm pH = \rm - log \rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%20pH%20%20%3D%20%5Crm%20-%20log%20%20%5Crm%20%5BH%5E%7B%2B%7D%5D)
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.

Answer:
kb = 2,0x10⁻⁵
Explanation:
The ka for HCN is:
HCN ⇄ H⁺ + CN⁻; ka = 4,9x10⁻¹⁰ <em>(1)</em>
The inverse reaction has an equilibrium constant of:
H⁺ + CN⁻ ⇄ HCN k = 1/4,9x10⁻¹⁰ = 2,0x10⁹ <em>(2)</em>
As the equilibrium of the water is:
H₂O ⇄ H⁺ + OH⁻; kw = 1x10⁻¹⁴ <em>(3)</em>
The sum of (2) + (3) gives:
H₂O + CN⁻ ⇄ HCN + OH⁻; kb = kw×k = 1x10⁻¹⁴×2,0x10⁹ =
2,0x10⁻⁶; <em>kb = 2,0x10⁻⁵</em>
<em />
<em>-In fact, the general formula to convert from ka to kb is:</em>
<em>kb = kw / ka-</em>
