Cream of tartar was often used in traditional dyeing where the complexing action of the tartrate ions was used to adjust the solubility and hydrolysis of mordant salts such as tin chloride and alum. Cream of tartar, when mixed into a paste with hydrogen peroxide, can be used to clean rust from some hand tools, notably hand files. The paste is ...
This is a common method used in households to remove a variety of stains. Depending on the stains composition, the stained material is left to soak in a container of warm or cool water and solvent. Such solvents can include laundry detergent, bleach, peroxide, vinegar, or a cleaning product with enzymes.
A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide. [2] [3] As hydrogen peroxide is less stable at high pH than under acidic conditions, NH 4 OH (pH c. 11.6) also accelerates its decomposition.
Oil of tartar – concentrated potassium carbonate, K 2 CO 3 solution; Oil of tartar per deliquium – potassium carbonate dissolved in the water which its extracts from the air. Oil of vitriol/spirit of vitriol – sulfuric acid, a weak version can be formed by heating green vitriol and blue vitriol. H 2 SO 4
Racemic tartaric acid can be prepared in a multistep reaction from maleic acid. In the first step, the maleic acid is epoxidized by hydrogen peroxide using potassium tungstate as a catalyst. [23] HO 2 CCH=CHCO 2 H + H 2 O 2 → HO 2 C(CHCH)(O)CO 2 H + H 2 O. In the next step, the epoxide is hydrolyzed. HO 2 C(CHCH)(O)CO 2 H + H 2 O → HO 2 CCH ...
The combination of salt and vinegar should have loosened the rust, making it easier to remove. Continue scrubbing until the rust is gone or significantly reduced. Step 5: Neutralize the Acid
It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate. [1] Potassium bitartrate, also referred to as potassium acid tartrate or cream of tartar, [2] is the potassium acid salt of l-( + )-tartaric acid. It is obtained as a byproduct of wine ...
In the wash, both compounds dissolve in the water. When dissolved in water, the persalt releases hydrogen peroxide (e.g. from sodium percarbonate): 2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2. In a basic wash solution, hydrogen peroxide loses a proton and is converted to the perhydroxyl anion: H 2 O 2 ⇌ H + + HO 2 −
