Titration is a method used in chemistry laboratories to determine the concentration of a substance in a solution.  In a titration, a carefully controlled volume of solution of known concentration is added to the unknown solution by means of a buret.
Variables:
m = slope
Ka = ionization constant
x = half equivalence point
y = pH
x1,x2 = x coordinate
y1,y2 = y coordinate
Formulas used:
m = (y2 - y1) / (x2 - x1)
this formula calculates slope
y - y1 = m(x - x1)
this formula calculates the equation needed to find pH
y = mx + b
this equation calculates pH values
ka = 10^-pH
this formula calculates ionization constant
