         6 . A method, comprising:
 running a reactor in a first mode;   wherein the first mode comprises:   producing base and hydrogen gas from a first electrode;   producing acid and oxygen gas from a second electrode that is electrochemically coupled to the first electrode in the reactor; and   allowing the oxygen gas to diffuse and/or be transported to the first electrode and/or allowing the hydrogen gas to diffuse and/or be transported to the second electrode; and   allowing the oxygen gas to be reduced by the first electrode and/or allowing the hydrogen gas to be oxidized by the second electrode.   
     
     
         7 . The method of  claim 6 , further comprising collecting the acid and/or base. 
     
     
         8 . The method of  claim 6 , further comprising reacting the collected acid and/or base in a chemical dissolution and/or in a precipitation reaction. 
     
     
         9 . The method of  claim 6 , wherein the producing acid from the second electrode and producing oxygen gas from the second electrode comprises oxidizing water by the second electrode to produce oxygen gas and acid. 
     
     
         10 . The method of  claim 6 , wherein the producing base from the first electrode and producing hydrogen gas from the first electrode comprises reducing water by the first electrode to produce hydrogen gas and base.

         13 . The method of  claim 11 , comprising reacting the collected acid in a chemical dissolution. 
     
     
         14 . The method of  claim 12 , comprising reacting the collected base in a precipitation reaction. 
     
     
         15 . The method of  claim 1 , further comprising storing the acid and/or base. 
     
     
         16 . The method of  claim 1 , comprising storing the acid. 
     
     
         17 . The method of  claim 15 , comprising storing the base. 
     
     
         18 . The method of  claim 1 , further comprising running the reactor in a second mode, wherein a polarity of the reactor is reversed in the second mode compared to a polarity of the reactor in the first mode. 
     
     
         19 . The method of  claim 18 , wherein a cost of electricity for running the reactor in the first mode is a first cost and an availability of electricity for running the reactor in the first mode is a first availability, wherein a cost of electricity for running the reactor in the second mode is a second cost and an availability of electricity for running the reactor in the second mode is a second availability, and wherein the second cost is greater than the first cost and/or the first availability is greater than the second availability. 
     
     
         20 . The method of  claim 18 , wherein the method further comprises collecting and storing the base, and the second mode comprises adding the stored base to the reactor near the second electrode.
