Task 1: Producing a graph to represent solubility data
| Potassium nitrate (KNO3) | Sodium nitrate (NaNO3) | |
|---|---|---|
| Temp. °C | g / 100 g water | g / 100 g water |
| 20 | 32 | 88 |
| 30 | 45 | 96 |
| 40 | 63 | 105 |
What happens when you stir a spoonful of sugar into hot water answers?
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

Does the military put saltpeter in food?
“Saltpetre,” (the term refers either to potassium or sodium nitrate) has no effect on carnal urges. The story that this chemical was put into soldiers’ food to decrease their sex drive is a total myth. The story that this chemical was put into soldiers’ food to decrease their sex drive is a total myth.
Is saltpeter a poison?
Saltpeter and other nitrates have a long history of medical use, but it is toxic in high doses and can produce symptoms ranging from a mild headache and upset stomach to kidney damage and dangerously altered pressure.
What food has the most nitrates?
Leafy vegetables, such as lettuce or spinach, contain the highest concentrations of nitrate (Iammarino, 2014). Approximately 80% of dietary nitrates are derived from vegetable consumption.
Why are nitrates bad?
Sodium nitrate, a preservative that’s used in some processed meats, such as bacon, jerky and luncheon meats, could increase your heart disease risk. It’s thought that sodium nitrate may damage your blood vessels, making your arteries more likely to harden and narrow, leading to heart disease.
Does sea salt contain nitrates?
According to the National Academy of Sciences (1981), vegetables were found to contain 1,500 to 2,800ppm nitrate. Sea salt has been suggested as a possible source of nitrate; however, limited analytical information suggests that the nitrate content of sea salt is relatively low (Sebranek and Bacus, 2007b).
