An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. ... The word acid comes from the Latin words acidus or acere, which mean "sour," since one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).
In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH−) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons ...
In chemistry, a salt is an ionic compound which is made up of two groups of oppositely charged ions. ... The salt we put on our fries is actually sodium chloride and is made up of a Na1+ (that's our metal) and a Cl1- (our non-metal). Often you will see this written as Na+ and Cl- (the 1 is dropped), or simply NaCl.
