pH alteration

Function for calculation of the new pH after adding a strong acid or base

File name: 'delta_pH'. A function for calculating the
alteration of the pH when a certain volume of a strong
acid or base is added.
Five input values: 'pH_start', V_start, V_added
'conc_solution' and 'type'

One output value: 'pH'

pH_start: Initial pH
V_start: Inital volume (mL)
V_added: Added volume of acid/base (mL)
conc_solution: Concentration of the acidic or basic solution (M)
type: Acid or base

Input syntax: pH = delta_pH(pH_start,V_start,V_added,conc_solution,type)
