[oh-]=3.0*10^-2M
Is it a base neutral or acidic
bases, conc OH is >1*10^7
this is almost 10,000 stronger on OH concentration
To determine if a solution is neutral, acidic, or basic, we need to know the pH value. The pH of a solution can be calculated using the concentration of hydrogen ions ([H+]) or hydroxide ions ([OH-]).
In this case, you've provided the concentration of hydroxide ions ([OH-]), which is 3.0*10^-2 M. The pH of a solution can be calculated using the formula:
pOH = -log[OH-]
To calculate the pOH, we can plug in the given value of [OH-]:
pOH = -log(3.0*10^-2) ≈ 1.52
To determine if the solution is neutral, acidic, or basic, we can use the relationship between pH and pOH:
pH + pOH = 14
Therefore, we can calculate the pH:
pH = 14 - pOH
pH = 14 - 1.52
pH ≈ 12.48
With a pH value of approximately 12.48, the solution would be considered basic.
To determine whether a solution is neutral, acidic, or basic, you need to examine the concentration of hydrogen ions (H+) or hydroxide ions (OH-) in the solution. In this case, you have been given the concentration of hydroxide ions ([OH-]).
In a neutral solution, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-). Therefore, to determine the nature of the solution, you can calculate the concentration of hydrogen ions by using the concept of the ionic product of water.
In pure water, at 25°C, the product of hydrogen ion concentration and hydroxide ion concentration is equal to 1.0 x 10^-14 M^2. This is represented by the formula: [H+][OH-] = 1.0 x 10^-14 M^2.
If you have the concentration of OH- in the given solution, which is 3.0 x 10^-2 M, you can plug in the value into the formula and solve for [H+].
Since [H+][OH-] = 1.0 x 10^-14 M^2,
[H+] = (1.0 x 10^-14 M^2) / [OH-].
Substituting the given value of [OH-], the calculation becomes:
[H+] = (1.0 x 10^-14 M^2) / (3.0 x 10^-2 M).
Now, you can calculate the concentration of hydrogen ions, [H+], using the equation above.
Once you determine the concentration of hydrogen ions, you can determine the pH of the solution using the formula: pH = -log[H+].
If the pH is less than 7, the solution is acidic. If the pH is equal to 7, the solution is neutral. If the pH is greater than 7, the solution is basic.
Therefore, by calculating the concentration of hydrogen ions using the given concentration of hydroxide ions and then determining the pH, you can determine whether the solution is neutral, acidic, or basic.
