Answer:
Soil minerals form the basis of soil. 
Explanation:
They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
 
        
             
        
        
        
 is most abundant and 6310 times more than HF.
<h3>What is a strong and weak acid?</h3>
When an acid is dissolved in water, all of its molecules disintegrate, making the acid powerful.
When an acid is dissolved in water, only a small number of its molecules disintegrate, making the acid weak. Strong acids have a lower pH than weak acids. 
The powerful acids include perchloric acid, chloric acid, nitric acid, sulfuric acid, hydrobromic acid, and hydroiodic acid. 
Given: 
Pka=3..2
pH=7
Let the volume be 1 liter
[HF]=01 M

Now,

F-:HF= 6309.57:1
Therefore, the most abundant is 
and has 6310 times more than HF is 
.
