The formula for pH is pH = -log[H+].
The formula for slope is m = (y2 -y1)/(x2 - x1)
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
How can you calculate pka valve if ph is given?

To calculate the anticipated pH you need to have a balanced equation of your reaction, use the appropriate Ka or Kb values and determine the anticipated amount of excess ions and whether they are H+ or OH-. These will determine your pH.
point-slope formula and finding the slope of the line.
the formula used to calculate a slope is: m=y2-y1/x2-x1
the formula used to calculate a slope is: m=y2-y1/x2-x1
the formula used to calculate a slope is: m=y2-y1/x2-x1
Depending on its concentration you can calculate it by this formula: pH = -log[H3O+]
Using limits and the basic gradient formula: rise/run.
You can use the formula: y=mx+b (berdill)
(X1,Y1) (X2,Y2)Step One: Identify two points on the line.Step Two: Select one to be (x1, y1) and the other to be (x2, y2).Step Three: Use the slope equation to calculate slope.
Slope can be calculated with the slope formula. This formula is: m (slope) = second y point - first y point / second x point - first x point Applying this formula to this problem, you get: 3-4/2-6 = -1/-4 = 1/4 The slope of (6,4) and (2,3) is 1/4.
how calculate slope mh to mh
Calculate slope as slope=(y2-y1)/(t2-t1).
Ist step, calculate pOH value by using formula pH + pOH = 14 2nd step, pOH = -log[OH], [OH] = - Antilog of pOH
it is the slope formula in the equation it is the slope formula in the equation
