Question
Consider the reversible reaction below. Then answer the questions below. H_2 CO_3 + OH^- HCO_3^- + H_2 O During acidosis, would the pH of the solution that this reaction occurs in increase or decrease? During acidosis, which direction, left or right, would this reversible reaction shift in order to maintain its equilibrium? Write the chemical formula of the buffer system present in the above chemical change. Which of the following is true for the basic salt Na_2 PO_4? NaOH is a strong base H_3 PO_4 is a strong base H_3 PO_4 is a strong acid NaOH is neutral Where do the exchanges occur in a nuclear equation?
