A water solution is found to have a molar oh- concentration of 3.2 x 10-5. the solution would be classified as neutral.
The concentration of hydroxide ions (OH-) is measured by pOH. It is a way of expressing how alkaline a solution is. At 25 degrees Celsius, aqueous solutions with pOH values of 7 or less are neutral, whereas those with pOH values of 7 or more are acidic. The hydrogen ion potential is known as pH. The potential of hydroxide ions is known as pOH. 2. It is a scale used to estimate the hydrogen ion (H+) concentration in the solution. The hydroxide ion (OH-) concentration of the solution is measured using this scale.
pH + pOH = 14
pOH = 3.2x 10-5
[OH-] = 10^(-pOH) =10^(- 3.2x 10-5)
= 0.99
Answer:
~0.0004
Explanation:
n=0.072/(56+(35.5*3))=0.072/162.5~~0.004

Answer:
The amount of water in a 95 mL sample of the solution is 33.25 mL
Explanation:
65% (v/v) rubbing alcohol is a solution containing 65 mL rubbing alcohol in 100 mL solution of the rubbing alcohol and water
Therefore, 95 mL sample of the solution will contain x mL of rubbing alcohol;
x = 65% × 95 = 0.65 × 95 = 61.75 mL rubbing alcohol and therefore, the amount of water contained = 95 - 61.75 = 33.25 mL
The amount of water in a 95 mL sample of the solution = 33.25 mL.
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important –<u> mass, and distance</u>. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
