Question

What electrolyte can be used in the salt bridge of a galvanic cell that has nickel {Ni(NO3)2} and zinc {Zn(NO₃)₂} electrodes, and why? What will be the ion flow in the solutions?

Answer 1

salt bridge used to maintain electrical neutrality, within the internal circuit Ni / Ni(nusz act as Cathodic half cell here wi (NO3)2 Nics) + 2003 In a Cathodic half rell Nož ions produce, to make neutral , Salt bridge produce positive ions ie kt long Lulzo (Noyz - Anodic half ceu oxidation of Ln takes place LMIS - Lonto the Inty ione produce, to make elechiced neutrality, Salt bridge produce 8 positive negative ione , non ions The Salt bridge used in the galvanic cell if KNO. 14 - well ist Nilnik inir

cathode anode kt ions moving from Salt bridge into Cathode to balance out the excess Nož ione into anode to Nos ione moving from balance out the excess salt bridge Lotions. kt & Noz firms Salts with metals, there are soluble in water, does not Srin any precipitate, So we used KNO3 as Salt bridge in the above Galvanic cell.
