Is a dilute solution of perchloric acid is considered a weak acid or a strong acid? ANSWER: 4.2*10^-13 Explain. What does a seismograph record? pH= 11.358, Since Sr(OH)2 is diprotic so we first multiply by two In the simulation, open the Micro mode, then select the solutions indicated below from the dropdown above the beaker in the simulation. of phosphoric acid Based on this observation, which statement below best describes the pH of a 0.1 M solution of lactic acid, HC3H5O3, (Ka 1.4 104)?
