How might you determine the concentration of a strong acid using a standard potassium thiosulfate solution, potassium iodide, and a standardized solution of sodium thiosulfate?
please can you just tell me each of these reactions are oxidation or reduction :
1-extracting metals in blast furnace
2-butter going rancid
3-electroplating
3-rusting
4-combustion
5-respiration
6-paint drying
7-fireworks and rockets
Thank you for your help and am waiting your answer
