Strength of Acids
More Results Here are some Pictures of my test. LIME COKE AND LIME COKE VINEGAR WATER
Discussion At first I thought the Coke would Corrode the nails the most instead of Water, Lime and Vinegar. But I was wrong the Vinegar did something really weird it lost 0.1 grams I’m not sure how but my Hypothesis is that the nail in the Vinegar ate the inside of the nail that’s why it got litter. The other thing was that the water turned gold and was really rusty.
Conclusion I reckon that the Water did the best rusting out of all of them and the Coke second best Vinegar third coke and lime fourth and Lime last. So thank you for watching my Report hope you enjoyed.
