How is chalk in toothpaste collected?
Chalk used in toothpaste is typically collected from natural deposits or synthetically produced. Natural chalk deposits are mined from underground and then processed to remove impurities. Synthetic chalk is manufactured by combining calcium carbonate and other ingredients. Once collected, the chalk is finely ground and purified to be used in toothpaste formulations.
What solid dissolves best in water are twenty degrees Celsius salt sugar iodine chalk or urea?
Sucrose is the most soluble.
Why does salt melt ice faster than sugar or sand?

Why does chalk dissolve in lemon juice?
Lemon juice contains citric acid. Citric acid is a weak acid that has the chemical formula of C6H8O7. It reacts with chalk, which consists of calcium carbonate (CaCO3). Whenever an acid reacts with a base, a salt and water are formed. Salts can dissolve in water (they are aqueous). Therefore, when chalk reacts with lemon juice, water and aqueous sodium citrate are formed. The sodium citrate dissolves into the water.
When you mix chalk with water and then evaporate the water what do you have?
