Mass would crystallize out : 24 g
<h3>Further explanation
</h3>
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
-
1. Temperature:
-
2. Surface area:
-
3. Solvent type:
-
4. Stirring process:
We can use solubility graph to solve this.
solubility KClO₃ at 90°C=52 g
solubilty KCl₃ at 60°C= 28 g
Mass would crystallize out = 52 - 28 =24 g

Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.
Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.
Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.
HF and NaF - If the right concentrations of aqueous solutions are present, they can produce a buffer solution.
<h3>What are buffer solutions and how do they differ?</h3>
- The two main categories of buffers are acidic buffer solutions and alkaline buffer solutions.
- Acidic buffers are solutions that contain a weak acid and one of its salts and have a pH below 7.
- For instance, a buffer solution with a pH of roughly 4.75 is made of acetic acid and sodium acetate.
<h3>Describe buffer solution via an example.</h3>
- When a weak acid or a weak base is applied in modest amounts, buffer solutions withstand the pH shift.
- A buffer made of a weak acid and its salt is an example.
- It is a solution of acetic acid and sodium acetate CH3COOH + CH3COONa.
