Because, of course, all these salts come from an acid + a base. If the salt comes from a STRONG acid and weak base, the pH will be acidic (<7) If the salt comes from s STRONG base and a weak acid, the pH will be basic (>7)
WebIf the equilibrium concentration of H2 is .44 M, find the equilibrium constant (Kc) for the reaction. .038 Consider the following reaction. At 175 K, the Kp for this reaction is 4.7x10^-4 and the intial pressures in the reaction vessel are PH2=P12=.626 atm, and PHI = .106 atm. WebThe pH of a buffer depends on the ratio [base]/[acid] rather than on the particular concentration of a specific solution. The exact ratio of the base to the acid for a desired pH can be determined from the K a value and the Henderson-Hasselbalch equation. For example: Suppose you wish to prepare a buffer solution to keep the pH at 4.30.
