A) Washing up - When using anionic surfactants and soaps, these neutralise the fatty acids in the oil and produce esters (Known as esterification) B) Washing powder - The principle is the same as A), but the alkali is not soap, but rather NaOH produced by the temporary hydrolysis of Na2CO3: Na2CO3 + H2O <--> NaOH + H2CO3 Because NaOH is a stronger base than H2CO3 is acidic, the solution is overall alkali.
10 to 11
sodium carbonate
yes
Well yea ... der. If washing powder couldn't dissolve than whats that point of having it? Once you put the powder in the machine, either front loader or top loader, the powder will start dissolving once you start the machine. Some washing powders don't dissolve very well but they do dissolve a some. hope i helped... xx
Yes, it is. You can tell weather something is an Alkali, Neutral pr acid via the pH scale or, you can tell if something is an alkali from its consistency; if it is sludgy (like washing-up liquid), it is an alkali. So, I am under the influence that washing-up POWDER is too, an alkali.J.S.P. Aged 11
pH 10 to 11 so it's an alkali
It will go a pink purple couler indicating that it is an alkali.
The most commonly used alkalis in washing powder are caustic soda and caustic potash. They are chemically produced by running electricity through salt water.
Washing up liquid, is a main one. Also, washing up powder. Im not sure of any others.
Yes it is an alkali.
The examples of the alkali are the washing products, soap, shampoo, and the washing up liquids.
Yes it is
It is an alkali its scientific name is sodium carbonate :)
It's an acid
It is an alkali its scientific name is sodium carbonate :)
Washing powder doesn't contain acids.
