Is hydrocyanic acid a strong or weak acid
WitrynaThe main difference between weak and strong solutions is indeed that for strong solutions we are given a Brownian motion on a given probability space whereas for weak solutions we are free to choose the Brownian motion and the probability space. ... Examples of weak electrolytes are Acetic Acid( C H 3 C O O H ) and Carbonic Acid ( … WitrynaSalts As Acids or Bases Example: NH 4 F 16 26 NH 4 F NH 4 + F-conjugate of conjugate of NH 3 HF weak strong So NH 4 + is ACIDIC So F-is BASIC NH 4 + is the conjugate acid of NH 4 OH which is the same as NH 3 (aq) F − is the conjugate base of HF K a > K b, so NH 4 F is acidic NH 3 is a weak base, so NH 4 + is acidic HF is a …

WitrynaWeak acids, such as ethanoic acid (CH 3 COOH), do not fully dissociate. In fact, about only one per cent of ethanoic acid molecules split up to form H + ions and CH 3 COO – ions at any one time. WitrynaStrong and Weak Acids and Bases . Many hardware stores sell "muriatic acid" a 6 M solution of hydrochloric acid HCl(aq) to clean bricks and concrete. Grocery stores sell vinegar, which is a 1 M solution of acetic acid: CH 3 CO 2 H. Although both substances are acids, you wouldn't use muriatic acid in salad dressing, and vinegar is ineffective …
