What is the sum of pH and pOH in any solution?
ONLY in pure water at 25 0C :pH + pOH = 14.00
What are some numbers that epual 30?
6 x 5 25 + 5 35 - 5 150 ÷ 5
What is the pOH of pure water at 60C?
pH = -log(concentration of H+ ion) which indicates acid pOH = -log(concentration of OH- ion) which indicates base In pure water at 25 degree Celsius, concentration of H+ and OH- is equal i.e. 10^-7 mol/dm^3 so, the sum of pH and pOH is -log(10^-7) + -log(10^-7) = 7 + 7 = 14
What two numbers epual 250?
1 x 250, 2 x 125, 5 x 50, 10 x 25 and 125 + 125 = 250
How do you find pH and poh of a 0.002614M NaOH solution?
First, since NaOH is a base you have to find the pOH first so you use the equation -> pOH = -log[NaOH] pOH = -log[NaOH] = -log[0.0111] pOH = 1.955 Then you use this equation -> 14 = pH + pOH to find the pH 14 = pH + pOH pH = 14 - pOH = 14 - 1.955 pH = 12.045 and that makes it basic Hope that helped. ^_^
Sum of 1st 25 prime no?
The sum of the first 25 prime numbers is 1,060.
What is the sum of the first 25 multiples of 12?
The sum of the first 25 numbers is 25*26/2 = 325 So the sum of the first 25 multiples of 12 is 325*12 = 3900

What is the total when 10 is added to the sum of 25 an 52?
The total sum is: 25+52+10 = 87
Prepare 5 M NaOH of pH 12?
na+oh +25=53 ph+poh=2.3
Find the sum of the counting numbers from 1 to 25?
Sum of 1,2, ... , n is n*(n+1)/2 Here, n = 25 so sum = 25*26/2 = 325
