Buffer equations chemistry
WebMobile phase composition was found to be less differentiating, although for some compounds a pH effect was noted. Unsurprisingly, chemical structure was found to be the dominant factor for ESI response for the majority of the investigated analytes, representing about 85% of the replicating detectable complement of the sample data set. WebExample: Calculate the ratio of ammonium chloride to ammonia that is required to make a buffer solution with a pH of 9.00. The Ka for ammonium ion is 5.6 x 10-10. First, write the equation for the ionization of the ammonium ion in water and the corresponding Ka expression. Rearrange the equation to solve for the hydronium ion concentration.
