Which is strong electrolyte potassium chloride or calcium chloride?
Both potassium chloride and calcium chloride are strong electrolytes when dissolved in water or when molten.
Which substance is least soluble at 60 degrees C?
Silver chloride is least soluble at 60 degrees C compared to sodium chloride, potassium chloride, and calcium chloride.
What are the 10 most common salts?
Examples are: sodium chloride, potassium chloride, calcium chloride, ammonium chloride, ammonium phosphates, sodium carbonate, sodium sulfate, magnesium sulfate, cooper sulfate, magnesium chloride.
What are 5 substances?
Pure water is a neutral substance. Other examples are sodium chloride, calcium chloride, potassium nitrate, ammonium nitrate, copper sulfate, magnesium sulfate, calcium carbonate, and sodium hydrogen carbonate.
Why it is unlikely that calcium chloride crystals are made from calcium metal?
It is unlikely that calcium chloride crystals are made from calcium metal because calcium is a rare and very expensive metal, also very susceptible of corrosion in normal air.It is much easier to start with limestone (CaCO3) and dissolve it with hydrochloric acid. Carbon dioxide is released and the excess of water should be evaporated after filtering of the undissolved particles of the limestone impurities.(CaCO3)s + (impurities of limestone)s + (HCl)l => (CaCl2)s + (CO2)g + (H2O)evap ++ [impurities of limestone]filter
Which is strong electrolyte potassium chloride or calcium chloride?
Both potassium chloride and calcium chloride are strong electrolytes when dissolved in water or when molten.
How would you obtain pure crystals of calcium chloride?
To obtain pure crystals of calcium chloride, you can start by dissolving calcium chloride in water to form a saturated solution. Then, allow the solution to cool and evaporate slowly, which will cause calcium chloride crystals to form. Once the crystals have formed, they can be filtered and dried to obtain pure crystal calcium chloride.
Will calcium chloride and potassium react?
Yes. The potassium will replace the calcium in the calcium chloride, producing potassium chloride and calcium. This is an example of a single replacement/displacement reaction. CaCl2 + 2K --> 2KCl + Ca
Does calcium chloride react with potassium iodide?
Yes, calcium chloride and potassium iodide can react with each other to form calcium iodide and potassium chloride. This reaction results in the exchange of ions between the two compounds.
Which substance is least soluble at 60 degrees C?
Silver chloride is least soluble at 60 degrees C compared to sodium chloride, potassium chloride, and calcium chloride.
How crystals of calcium chloride made from calcium carbonate and dilute hydrochloric acid?
Crystals of calcium chloride can be made from calcium carbonate and dilute hydrochloric acid through a chemical reaction where calcium carbonate reacts with hydrochloric acid to form calcium chloride, carbon dioxide gas, and water. The resulting solution can be further evaporated to allow crystals of calcium chloride to form.
What are the formulas for calcium chloride and potassium phosphate?
The formula for calcium chloride is CaCl2, indicating that it consists of one calcium cation (Ca2+) and two chloride anions (Cl-). The formula for potassium phosphate is K3PO4, showing that it consists of three potassium cations (K+) and one phosphate anion (PO43-).
What are formulas for calcium chloride and patassium phosphate?
Calcium chloride has the formula CaCl2 if anhydrous. Potassium phosphate has the formula K3PO4.
What happens when you add calcium chloride to potassium carbonate?
When you add calcium chloride to potassium carbonate the products will be solid calcium carbonate and aqueous potassium chloride. The chemical equation for this reaction is CaCl2(aq) + K2CO3(aq) --> 2KCl(aq) + CaCO3(s). This type of reaction is called a double replacement/displacement reaction.
How many grams of calcium chloride are needed to produce 10 g of potassium chloride?
To find the amount of calcium chloride needed, you would first need to determine the molar ratio between calcium chloride and potassium chloride in the chemical reaction. Then, you could use this ratio to calculate the amount of calcium chloride required to produce 10 g of potassium chloride. The molar ratio is 1:1, so the same amount of calcium chloride as potassium chloride, 10 g, would be needed.
What does the difference between the few crystals of anhydrous calcium chloride and a few crystals of Glauber's salt when are exposed to the atmosphere?
Calcium chloride easily absorb water, it is hygroscopic.
Predict the formulas for calcium chloride and potassium phosphate?
The formula for calcium chloride is CaCl2, and the formula for potassium phosphate is K3PO4.
