-Inert
-Inert means that a substance does not react chemically with other substances. In the context of IAVS (Integrated Aqua-Vegeculture System), inert sand is sand that does not react chemically with water or other substances in the system.
-This is important in IAVS because sand that is not inert can affect the pH of the water and lead to nutrient deficiencies for the plants. Inert sand ensures that the pH of the water remains stable and that the plants receive the necessary nutrients for healthy growth.
-Vinegar Test
-Vinegar can be used to test whether sand is inert, which is an important characteristic of iAVS-Suitable Sand. Inert sand is sand that does not react chemically with water or other substances in the system. This is important in IAVS because sand that is not inert can affect the pH of the water and lead to nutrient deficiencies for the plants.
-To use vinegar to test whether sand is inert, a small amount of sand should be placed in a jar or bottle lid. Then, vinegar should be poured over the sand. If the sand is inert, there should be no reaction between the vinegar and the sand. However, if the sand is not inert, it will react with the vinegar and produce bubbles or fizzing. This is because the vinegar reacts with substances in the sand, such as carbonates, which can affect the pH of the water in the IAVS system.
-If the sand produces bubbles or fizzing when vinegar is poured over it, it is not inert and should not be used in an IAVS system.
