The nitrates in the soil in the beakers could increase during an investigation due to the breakdown of organic matter in the soil, the addition of nitrogen-containing fertilizers, or the release of nitrates from decomposing plant material. These factors can contribute to the accumulation of nitrates in the soil over time.
Beakers are not typically used for precise measuring due to their lack of graduated markings. They are better suited for holding and mixing liquids during experiments. For accurate measurements, it is recommended to use graduated cylinders or volumetric glassware.
Nitrates are commonly used as sources of metal ions because they are water-soluble and can easily dissociate into metal cations and nitrate anions in solution. This allows for easy separation and purification of the metal ions during various chemical processes. Additionally, nitrates are generally stable compounds that do not decompose easily, making them convenient sources of metal ions for laboratory and industrial applications.
The four stages of the nitrogen cycle are nitrogen fixation, nitrification, assimilation, and denitrification. During nitrogen fixation, nitrogen gas is converted into ammonia by bacteria. Nitrification involves the conversion of ammonia into nitrites and nitrates. Assimilation is the process of incorporating nitrogen into living organisms. Denitrification converts nitrates back into nitrogen gas.
Nitrate is mined from natural deposits of caliche ore . These deposits are mined primarily from saline mineral deposits that form veins and irregular masses in the bedrock. The ore is extracted by first drilling or blasting the soil overburden covering the deposits, then transported to the extraction plant. The overburden, usually 1 to 2 m thick, is removed mechanically and left on-site (Collings 1950). During refinement, crushed ore is dissolved at 35°C to extract nitrates, sulfates, potassium, and iodine. Nitrate precipitates are removed, crystallized, dried, and prilled.
Why is it necessary to use iodine during this investigation
They are heat and chemical resistant. I HOPE I HELPED :D
It will increase due to osmosis
Nitrates are used to make explosives.

You take notes during an investigation, and write a report when the investigation is finished.

During heavy rain or flooding, excess water can leach nitrates from the soil, washing them away and making them inaccessible to plants. This process is known as leaching, and it occurs because water carries the nitrates deeper into the soil layers or even into nearby water bodies, reducing the amount of nitrates available for plant uptake.
it has to much rain in it
Beakers are used to measure and hold liquids in laboratory settings. They are typically used for mixing, heating, and pouring liquids during experiments.
Which factor does the investigator change during an investigation?
Beakers are important in laboratories for measuring and mixing liquids, as they offer good visibility and can withstand heating and cooling. They are also convenient for storing, pouring, and transferring liquids during experiments.
