The concentration of hydroxide ion of a solution with a pH of 8. 25 is 1.77×
M
Calculation,
The pH of a solution tells us about concentration of the 
ion ( proton ) in solution. However, if we know the value of pH , we can calculate pOH with the help of pH and from pOH we can find concentration of hydroxide ions in the solution.
pH + pOH = 14
8. 25 + pOH = 14
pOH = 14 - 8. 25 = 5.75
Since, pH = -㏒[ ]
Similarly, pOH = -㏒[
]
If pOH = 5.75 , that means that -㏒[ ] = 5.75 ,which means that,
[ ] = 
= 1.77×.
So, we know that the concentration of the ions in the solution with pH of 8.25 is 1.77× Molar

Answer:
molecule is a group of atoms bonded together representing the smallest fundamental unit of a chemical reaction
Answer:
The answer to your question is V₁ = 12.5 ml
Explanation:
Data
Volume = V₁?
[NaOH] = C₁ = 4.0 M
Volume 2 = V₂ = 100 ml
[NaOH] = C₂ = 0.5 M
Formula of dilution
V₁C₁ = V₂C₂
Solve for V₁ (original solution)
V₁ = 
Substitution
V₁ = 
Simplification
V₁ = 
Result
V₁ = 12.5 ml
The answer is B for number 1 because rather than it being an observation it is something that you know for sure happened without guessing.
the answer is B the researcher is actually adding the fertilizer and measuring it.
The answer to your question is Coefficients.
