The temperature when ice melts is 32 degrees Fahrenheit.
<span>Answer: option (1) solubility of the solution increases.
</span><span />
<span>Justification:
</span><span />
<span>The solubility of substances in a given solvent is temperature dependent.
</span><span />
<span>The most common behavior of the solubility of salts in water is that the solubiilty increases as the temperature increase.
</span><span />
<span>To predict with certainty the solubility at different temperatures you need the product solubility constants (Kps), which is a constant of equlibrium of the dissolution of a ionic compound slightly soluble in water, or a chart (usually experimental chart) showing the solubilities at different temperatures.
</span><span />
<span>KClO₃ is a highly soluble in water, so you do not work with Kps.
</span><span />
<span>You need the solubility chart or just assume that it has the normal behavior of the most common salts. You might know from ordinary experience that you can dissolve more sodium chloride (table salt) in water when the water is hot. That is the same with KClO₃.
</span><span>The solubility chart of KlO₃ is almost a straight line (slightly curved upward), with positive slope (ascending from left to right) meaning that the higher the temperature the more the amount of salt that can be dissolved.</span>
Answer:
Fat
Alkali
Explanation:
Fat and alkali are the two primary raw materials needed to manufacture soap.
Sodium hydroxide or potassium hydroxide is generally used as an alkali. The use of alkali depends on the intended application of the soap.
Raw animal fat was used in the past but these days, processed fat is used in the soap manufacturing process. Vegetable fats ( e.g, palm oil, olive oil, coconut oil) are also being used in soap manufacturing.
Additives are also used to enrich the color and texture of the soap.
It's most natural state has a charge of -2. So, a negative ion with two more electrons than is normal.
