Correlation Between Potato And Salinity : Investigating The Myth In The Internet

Current work focuses on investigating the rumours or myths saying that adding potatoes would be able to fix an oversalted dish, particularly soups. Based on our survey on the internet, there are various sources and blogs reporting yes and no. And the test they carried did not carry proper scientific and empirical methods. In this study, we carried out the experiment to test and find out if potatoes would be able to cause any effect on salinity through salt solution. With proper volume and mass measurement, salinity refractometer to record the salinity properly, and proper experimentation, we believe the rumours can be answered accordingly. The results showed that boiled potatoes immersed into salt solution (8%) indeed were able to reduce salinity up to 20 %. The potatoes did not act as an adsorbent, but functioned as water carriers allowing diffusion of salt ions from the concentrated solution into the less concentrated water region carried by the potatoes. In this abstract, we detailed out the methodology and further interpretation of the results.
