Strong and weak acids and basesPearson, Ralph G
Weak Acids and Bases A hydrogen atom is composed of a proton and an electron. A hydrogen ion has lost its electron and is just a proton. It is just a positive charge. A hydrogen ion (or proton) is usually represented by H+. An acid is a substance that, when mixed with water, ...
Strong acids completely dissociate in water to produce a hydronium ion and a very weak base. Weak acids only partially dissociate in water, so they only form a small percentage of hydronium ions and a weak base. Vinegar is a good example of a weak acid. Answer and Explanation: H...
Classify the compounds given below as a strong acid, weak acid, strong base, or weak base: Sr(OH)2 , HCN, HClO4, CsOH, NH3, H2SO3, HI The conjugate base of a weak acid is a weak base, why? Distinguish between strong acids and strong bases. ...
更新1: In this formular: eg of weak base: NH3 + H2O --- NH3+ + OH- Where did the another H+ went to?strong acid donates H+ and weak acid doesn't refuse to donate H+ weak acid also donates H+. no matter strong acid or weak acid when a substance in solu...
