NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis
<h3>Further explanation</h3>The hydrolysis process is a term used for the reaction of substances with water
There are 3 types of hydrolysis salts
1.Salt from strong acids and strong bases does not undergo hydrolysis so that the pH of the neutral solution = 7
2.Salt from strong acids and weak bases (pH <7) or from strong bases and weak acids (pH> 7) will be partially / partially hydrolyzed
3.Salt from weak acids and weak bases (pH depends on the value of Ka and Kb) will be completely hydrolyzed
NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis
NH₄OH + HCN⇒NH₄CN+H₂O
Can be formulated :
Ka> Kb then [H +]> 7 and pH <7 ⇒ acidic
Ka <Kb then [H +] <7 or pH> 7 ⇒alkaline
Ka = Kb then pH = 7 ⇒neutral
Answer: Photosphere
Explanation:
The Photosphere is the luminous surface that delimits the Sun as a star, besides being the coldest layer produces the light that is visible from the Earth. This surface is composed of a layer of gases that are subjected to strong pressures and its temperature is only (very cold compared to the
of its hottest layer).
However, there is anoter layer located above the Photosphere, the chromosphere; which shines with a reddish color and consists mainly of hydrogen and helium, and some metals in neutral state.
