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.

What reactions can occur with an acid?
Almost any reaction can involve an acid; the most common is the acid-base or neutralisation reaction.
What does neutalize mean?
neutralisation means nullifying the effect of one substance by another like in acid base reactions acid+base-salt(neutral)
What is the reaction called Between a Acid And Alkalie?
neutralisation.... i..think.................
Examples of endothermic and exothermic reactions?
Exothermic reactions give out energy overall. Here are some exothermic reactions:- Combustion of fuels such as hydrogen & methane- Neutralisation of an acid by an alkali- Reaction between sulphur & ironEndothermic reactions take in energy overall. Here are some endothermic reactions:- Reactions involved in cooking- The thermal decomposition of calcium carbonate- Photosynthesis in which plants use sunlight, carbon dioxide & water to make their own food
Write a short note on the examples for applications of neutralisation reaction in everyday life explain?
WikiAnswers will not do your homework for you. Nor will it write your discussion paper, critiques or essays. That is considered cheating. If you have a specific question in the subject we are more than willing to help
What Neutralisation can do in everyday life?
Basically neutralisation meansi t is a reaction between an acid and a baseto give neutral product i.e. neither acidic or basic is called neutralisation reaction. There are manny applications of neutralisation reactions. they are: In human beings agriculture soap industry textile industry food industry
How is the neutralisation reaction of ammonia and nitric acid different from most neutralisation reactions?
Because it doesnt have water
When an acid and an alkali react it is called combustion?
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
How is neutralisation useful?
because it helps us in our everyday life :D
What are neutralisation reactions?
Neutralization reactions are those that involve acids and bases. The products formed in a neutralization reaction is a salt and water.
What pH changes occur when Neutralisation reactions occur between two named acids and a named base?
Um I have a strange feeling your doing the junior cert :L
What is the method used to carry out an investigation to study the pH changes that take place when neutralisation reactions occur between two named acids and a named base?
Titration
How are the salts from neutralisation reactions named?
The salts obtained from neutralisation reaction are named by writing the name of cation followed by anion name. For example- The salt NaCl is named as sodium chloride.
Name some neutralisation equations?
neutralisation reactions are extremely useful... take for examaple when you have indegestion - you would take a Rennie's alkaline tablet to relieve you of the pain hope this is helpful
What reactions can occur with an acid?
Almost any reaction can involve an acid; the most common is the acid-base or neutralisation reaction.
What are the two common exothermic reactions in your everyday life?
Cooking food and Using fuels to run vehicles
Give Two examples of neutralisation reactions in everyday life?
When we severs stomach pain due to the acidity that formed in the mouth we use milk of magnesia Use of baking soda to neutralize an acid spill in industry Your own body does a neutralisation as food finishes in the stomach and goes into the small intestine where an alkaline environment is needed for the next enzyme reaction.
