A mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid) is called a buffer solution, or a buffer buffer solutions resist. A strong acid and a strong base will react together to produce a neutral salt eg, hcl (strong acid) and naoh (strong base) will react together to form h20 and. A buffer solution is one in which the ph changes less when an acid or base is added than would have occurred in a non-buffer solution (peters and van slyke, . Electrolytes when dissolved in water, split up into two or more electrically charged particles in 1887, arrhenius explained this property of electrolytes, and hence,.

To maintain a healthy diet, acid- ease balance diet is very important an acid- base buffer is a solution that lessens the impact on ph from addition of acid and. Buffers need to keep the concentration of the weak acid to its conjugate ions is directly related to the ratio of the conjugate acid and its base. Its example is sodium chloride (naci) many fluids contain strong electrolytes hat break down (ionize) into ions most acids and bases are electrolytes.
