Step 1: Pour about a cup of baking soda down the shower drain, followed by an equal amount of distilled white vinegar. Allow the solution to bubble and foam for a few minutes. Allow the solution ...
Drain Clog Remover. An affordable yet durable drain snake is good to have on hand for more serious drain clogs that require a bit of elbow grease, like in your bathtub, or if you have to unclog ...
Tile drainage. Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops. While surface water can be drained by pumping, open ditches, or both, tile drainage is often the most ...
Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [1] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...
A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [39] used for disinfection of waste water in treatment plants. Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [ 40 ] taking 0.2–2 mg of sodium hypochlorite per liter of water.
A hot water solution containing 73.1% (mass) of NaOH is a eutectic that solidifies at about 62.63 °C as an intimate mix of anhydrous and monohydrate crystals. [ 19 ] [ 18 ] A second stable eutectic composition is 45.4% (mass) of NaOH, that solidifies at about 4.9 °C into a mixture of crystals of the dihydrate and of the 3.5-hydrate.
After Drano crystals are added to water, the reaction works as follows: Aluminium reacts with lye: 2NaOH + 2Al + 2H 2 O → 3H 2 + 2NaAlO 2, although the exact species in solution may be NaAl(OH) 4. [1] The release of hydrogen gas stirs the mixture and improves the interaction between the lye and the materials clogging the drain.
Borax (also referred to as sodium borate, tincal (/ ˈtɪŋkəl /) and tincar (/ ˈtɪŋkər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17 (also written as Na 2 B 4 O 7·10H2O[1][a]). It is a colorless crystalline solid that dissolves in water to make a basic solution.
