How does the product look like when you mix sodium bicarbonate with calcium chloride?
How does it LOOK? Variations of this question have been posted over the last 3-4 days. I ASSUME the point is that we should see a white precipitate (insoluble material) of CaCO3 form. However, there is little carbonate ion in the solution from this mixture and, personally, I don't think any CaCO3 will form. Calcium BICARBONATE, [Ca(HCO3)2] is soluble; therefore, I don't think there will be any change in appearance for I don't think there will be a reaction.
CaCl2 + NaHCO3 ==> No reaction, I think.
Check my thinking. I shall be happy to listen to alternative reasoning; however, I think it will sit there and look back.
On more thought, there MAY be a way to get something else out of it. Bicarbonate, and it's essentially independent of concentration, produces a pH of about 8.3 (not very high so pOH is not very high) and NaHCO3 will produce a pH of about 8.3 when placed in water. IF the CaCl2 concentration is high enough, we MIGHT get a ppt of Ca(OH)2 but Ca(OH)2 is fairly soluble (1 L of pure water will dissolve about 1 gram of calcium hydroxide). Try it. Mix a handful of CaCl2 with a handful of baking soda and about a cup of water and see if that is enough to ppt Ca(OH)2. I don't know that I've tried this; I don't know if a ppt will form or not.
I did a quick calculation and I don't think it is feasible to get a high enough calcium concentration to form a ppt of Ca(OH)2. So my original thoughts are not changed; I think the solution will look back at you. If you find out differently, or anyone thinks differently, please let me know.
To determine how the product looks when sodium bicarbonate (NaHCO3) is mixed with calcium chloride (CaCl2), we first need to understand the reaction that occurs between these two compounds.
When sodium bicarbonate and calcium chloride are mixed together, a chemical reaction takes place. The reaction can be represented by the following balanced chemical equation:
2 NaHCO3 + CaCl2 → 2 NaCl + Ca(HCO3)2
In this reaction, sodium bicarbonate and calcium chloride react to form sodium chloride (NaCl) and calcium bicarbonate (Ca(HCO3)2) as products.
The appearance of the product will depend on the physical state (solid, liquid, or gas) and solubility of the compounds involved. Sodium chloride (NaCl) is a white crystalline solid, while calcium bicarbonate (Ca(HCO3)2) is a white powder.
So, when you mix sodium bicarbonate with calcium chloride, the resulting product is expected to be a mixture of white crystals and a white powder.
