I’m not sure but it has to be hydrogen
We can rewrite the equation KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq) into its net ionic equation into
K+ + Br- + Ag + + NO3- = AgBr + K + NO3-only aqueous solutions can dissociate. Spectator ions are present in both sides, hence these are K+ and NO3-. THe rules of assigning oxidation numbers is to identify the number of valence electrons of elements and may be arbitrary depending on the charge of the molecule.
(3); try using the phrase "AN OX ate the RED CAT"
(anode=oxidation, reduction=cathode)
Answer:
C.
Explanation:
The increase the [H+] (concentration of H+ ions)
However, they decrease the pH if acids are added to any solution. Since they have more [H+] ions, they increase their conc. in the solution
