Calcium Chloride | Formula, Properties & Application

Calcium chloride is generally obtained as a byproduct of the Solvay process, a method used for sodium carbonate production. During the Solvay process, limestone (CaCO 3) and salt (NaCl) are used as raw materials. The limestone is converted to lime (CaO), which reacts with water to produce calcium hydroxide (Ca(OH) 2). This substance then reacts ...

Limestone and dolomite aquifers are primarily calcium carbonate and calcium magnesium carbonate, respectively, but impure ones may contain as much as 50 percent noncarbonate constituents such as silica and clay minerals.

Project Based Lessons

Place ½ teaspoon calcium chloride in a cup. Add 25 mL of water and stir until the calcium chloride dissolves. Place about ½ teaspoon of calcium chloride solution into a small cup for each group. Place ¼ teaspoon sodium alginate powder in a plastic bottle. An empty disposable 8-oz plastic water bottle with a tight-fitting cap will work well.

Limestone origins

Metamorphic limestone. If, over time, a body of limestone has been squeezed and deformed by great heat and pressure deep beneath the Earth's surface, its structure and composition changes to form a recrystallised limestone known as marble, which can contain over 95% calcium carbonate. Marble is a hard crystalline rock that …

(a) Limestone, CaCO3, dissolves in muriatic acid, HCl,

here he stated limestone dissolves in hydrochloric acid to form calcium chloride, carbon dioxide and water. We have to write the balanced equation. Then we have to calculate how many miles of a CLR required to dissolve 5.4 molar calcium carbonate. And then we have to find out the moles of water that is found in part B.

Calcium Chloride Manufacturing Process | PDF

There are several methods for producing calcium chloride. The main methods are the Solvay process, which uses limestone and salt brine, the HCl process using hydrochloric acid and a calcium source, and using natural brine. Natural brine is often pumped from underground sources but can be inconsistent in strength and contain impurities. It is also …
