hydroxyl ions, called alkali Salt: a compound of metal ions and acid salts Illustrate: Acid: H2SO4 (sulfuric acid), HCL (hydrochloric acid), HNO3 (nitric acid) Alkali: NaOH (sodium hydroxide), KOH (potassium hydroxide), NH4OH (ammonia water) Salt: Na2CO3 (sodium carbonate), CuSO4 (c.....

记住carbonate不是base也不是alkali。因为base或alkali的定义是要与acid作出化学反应,只给出水与盐。而carbonate与acid的反应会产生carbon dioxide,所以不能算是base或alkali。 Neutralization (中和作用) acid + alkali/base → salt + water 参考: Physics king ...
(Chemistry) potential of hydrogen; a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution. Pure water has a pH of 7, acid solutions have a pH less than 7, and alk...
Acid + Base = Salt + water So, if NH3NH3 is a base then, it should be, Acid + NH3NH3 = Salt + Water But it does not happen. When reacting with acid, it doesn't produce water. For example, NH3+HCl⟶NH4ClNH3+HCl⟶NH4Cl -- Reference Again, NH3+H2SO4⟶(NH4)2SO4NH3+H2SO...
acid-base balance- (physiology) the normal equilibrium between acids and alkalis in the body; "with a normal acid-base balance in the body the blood is slightly alkaline" acid-base equilibrium physiology- the branch of the biological sciences dealing with the functioning of organisms ...
(acid), +CuO (metal oxide) = CuSO4 (salt), +H2O (water) Properties of alkali: Base + acid - (see acid property) Alkali + salt = new base + new salt reaction condition: alkali and salt must be dissolved in water, precipitate formation (two at the same time) Reaction type: ...
Base + acid - (see acid property)Alkali + salt = new base + new salt reaction condition: alkali and salt must be dissolved in water, precipitate formation (two at the same time)Reaction type: metathesisFor example: Ca (OH) 2 (alkali) +K2CO3 (salt) : =CaC03 (new salt) +2KOH (...
If HZ1 is a stronger acid (readily gives up hydrogen ions), then the conjugate base Z1- will not readily accept the hydrogen ion in the reverse reaction (definition of a weak base). HZ2 ⇔ H1+ + Z21- In this case HZ2, being weaker, does not give up its hydrogen ion as readil...
