all things are either acids or bases.acids are mostly sour.eg;orange.bases are mostly bitter eg;toothpaste.if a liquid produces more hydroxide,it is a base,and if a liquid produces more hydrogen,it is a acid.the acids and bases behave differently.acids take sour and they cause kerosene and bases are slippery.AVANTIKA MANOJ 7D

An acid is a chemical substance usually a liquid, which contains hydrogen and can react with other substances to form salts. Eg: Citric acid ,malic acid, lactic acid                                                                        A base is something that accepts a proton. Eg: Toothpaste, soap solution                                            Prathna Malani 7-D                                                                                                         very good

5.Acids are sour                                                                                                                                                          things can be tested whether they are acid or base by litmus paper there are two kinds of litmus         paper like red and blue litmus paper rd litmus paper says whether it is base. Blue litmus paper       says whether it is acid

# data[].attributes.body
4.Precautions taken while handling acids is the following:                                                                                   *inform someone when acid spills or if the tube breaks                                                                              *keep acids away from eye and the complete body                                                                                        *Do experiment under adult supper vision

DEFINITION: An acid is solution which donates a proton, while a base is a solution which attracts protons.                                                                                                                                                                           EXAMPLES: ACID- citric acid, Lactic acid, Tartaric acid, Hydrochloric acid, etc.                                                                     BASES- Baking soda, Soap, Cucumber, etc.                                                                                       TASTES: A base tastes bitter and an acid tastes sour.                                                                                                                                                                                                                                                                                         Joslin - 7D                                                                           Good

#a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base. Acids are proton donors that yield hydronium ions in water solution, or electron-pair acceptors that combine with electron-pair donors or bases.
a substance with a sour taste.
something, as a remark or piece of writing, that is sharp, sour, or ill-natured: 

# common examples of acids are hydrosulfuric acid, hydrobromic acid, hydrochloric acid, hydroiodic and hydrofluoric acid, while some common bases are calcium hydroxide, sodium hydroxide, barium hydroxide, ammonium hydroxide, magnesium hydroxide and potassium hydroxide

#Bases are often bitter tasting and have a slippery texture. However using taste and/or touch to identify a base is not recommended ,because touching or consuming a strong base is dangerous. 

#A base is a chemical species that donates electrons or hydroxide ions or that accepts protons#An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons

5Q.Can you propose definition for acid and base ?

ans) An acid is anything that donates protons and a base is anything that accepts a proton.We could also say that if a liquid produces more hydrogen it is an acid and if it produces more hydroxide it is a base.           Ahana 7A

4Q.  What are the safety precautions when using acids ?                                                            1. Safety glasses are to be worn whenever working with acids.                                                 2.Use plastic gloves when handling acid materials to prevent skin contact.                         3. Dispose used solutions in a responsible manner.                                                                  4. Clean equipment after usage.                          Ahana 7A

2.What are  the examples of acids and bases ?  ans )Examples of acids - Carbonic acid in soft drink, Citric acid in oranges and lemons, Acetic acid in vinegar etc                                  Examples of bases - ammonia in fertilizers and cleaning agents, sodium bicarbonate in baking soda, sodium carbonate in detergent etc                                                                              Ahana 7A
