Although soils are capable of resisting pH changes, there are some circumstances where the pH of the water can result in alterations.
<h3>Will Soil pH Be Affected by Water pH?</h3>
The texture of soil affects how susceptible it is to the pH of the surrounding water. Smaller soil particles, such as clays and clay loams, have a greater impact than larger, sandier soils. There are more colloids, which are extremely minute particles, in fine-textured soils. Positively charged ions are maintained at these colloids. The cation exchange capacity of a soil refers to its capacity to hold onto these ions. Ions on the colloidal particles trade places with ions in the soil solution. The pH of the soil is less affected by negative ions in the soil solution.

Answer:
77%
1.98/2.57= 0.770428016 = 77%
Answer: 1.
2.
3. .
4.
has highest nitrogen content.
Explanation:
To calculate the mass percent of element in a given compound, we use the formula:
1.
2.
3.
4.
Thus has highest nitrogen content of 82.4%.
The correct option is this: THE ATOMS IN THE SOLID WILL BE VIBRATING IN POSITION.
This is because the molecules in solids are held together by strong inter molecular forces, the molecules can not move about freely but they cab vibrate in their position.
Answer: C) It increases with a decrease in the concentration of . D) It decreases with increase in the concentration of .
Explanation: According to Le Chatelier's principle, if an equilibrium reaction is disturbed, the reaction would try to undo the change imposed.
Thus if the concentration of the products in increased, the reaction would shift in a direction where the concentration of products is decreasing i.e in backward direction.
If the concentration of the products in decreased, the reaction would shift in a direction where the concentration of products is increasing i.e in forward direction.
When the concentration of either of the products, i.e or is increased, the reaction will shift in backward direction and the rate of forward direction decreases.
