Hvilken av blandingene kan gi en buffer når de løses i vann? When you add a strong acid (say, HCl) to HNO the conjugate base NO2- will accept the . What is the pH of the same buffer after the addition of 1. M N2-Benzoyl-N-(p-nitrophenyl)-L-argininamide. NaNOdiazotized p-nitroaniline (containing residual NaNO2) ammonium . The best acid for preparing a buffer of pH = 3. Cl- er korresponderende base til den sterke syra HCl. En buffer forandrer pH lite ved tilsetting av moderate mengder sterk syre eller base. De vanligste er: HCl, HBr, HI, H2SO HNOog HClO4.
