How can we say that the acid or bases is strong or weak?
Answers
Answer:
Most acids and bases are weak, meaning that they do not completely dissociate into its ions, when we place them in solution. Only a few acids and bases are strong. Therefore, the key to master this topic is to learn the list of strong acids and bases that you can find below. If you are presented with an acid or base that is not on this list, that means that acid or base is weak. Is that simple! Laughing The STRONG acids are... HCL = hydrochloric acid HBr = hydrobromic acid HI = hydroiodic acid HNO3 = nitric acid H2SO4= sulfuric acid HClO3 = chloric acid HClO4= perchloric acid And the STRONG bases are... LiOH = lithium hydroxide NaOH = sodium hydroxide KOH = potassium hydroxide RbOH = rubidium hydroxide CsOH = cesium hydroxide Ca(OH)2 = calcium hydroxide Sr(OH)2 = strontium hydroxide Ba(OH)2 = barium hydroxide For example, is nitrous acid (HNO2) weak or strong? If we look at the list of acids, this one is not on the list, Therefore, nitrous acid is a weak acid Smile I hope this tip helps you understand this topic better! Please leave your comments and suggestions, and also let me know which chemistry topics would you like to read about. Smile I have many tips to share with you, so I look forward to your comments, thanks for reading my blog and have a wonderful week! Laughing
Answer:
Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid
Explanation:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid
