Explanation: Calcium chloride, CaCl2 , a soluble ionic compound, and sodium carbonate, Na2CO3 , also a soluble ionic compound, will react to form calcium carbonate, CaCO3 , an insoluble solid that precipitates out of solution, and sodium chloride, another soluble ionic compound.

Explanation: A chemical reaction occurs between the calcium chloride and the baking soda in which a double replacement reaction takes place. The two solids switch partners and form a new substance–the precipitate calcium carbonate.

The color changes were pink and hot pink in the overall reaction. The controlled experiments do not provide evidence concerning the combination of chemicals responsible for the observed color change because the phenol red solution was redand the dry substances were white so it just mixed to make pink.

High-dose calcium carbonate and sodium bicarbonate when taken together can cause a condition called milk-alkali syndrome. Its symptoms include headache, nausea, irritability, and weakness, hypercalcemia (high blood calcium levels), and reduced function of the kidneys.

Baking soda is alkaline and adding it to soil will reduce the acidity of soil. This less acidic soil produces less acidic tomatoes, which taste sweeter.

If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution. The reaction is: Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.

Using neutralisation Antacid tablets contain bases such as magnesium hydroxide and magnesium carbonate to neutralise the extra acid. Bee stings are acidic. They can be neutralised using baking powder, which contains sodium hydrogen carbonate.

Acid-Base Reactions Whenever you combine an acid (e.g., vinegar, lemon juice, sulfuric acid, or muriatic acid) with a base (e.g., baking soda, soap, ammonia, or acetone), you are performing an acid-base reaction. These reactions neutralize the acid and base to yield salt and water.

Add the distilled white vinegar to the fabric softener dispenser or add the vinegar manually at the beginning of the rinse cycle. The mild acetic acid in vinegar also acts as a whitener and brightener for gray, dingy clothes.

Bleach and vinegar can both kill mold, but vinegar is much more effective for removing mold from porous materials. This is because bleach only kills mold spores on the surface of affected materials. Vinegar will penetrate porous materials and kill the mold at the roots.

White vinegar is a mild acid that is known to kill roughly 82 percent of mold species, and it can even help prevent mold outbreaks in the future.

Soap and water alone won’t kill mold, but many common household cleaners do. You can get rid of pink mold in three basic steps. Other options for killing mold are 1 cup of borax (sodium borate) in 1 gallon of water, undiluted vinegar, or 3 percent hydrogen peroxide.
