C6H5NH3ClO2 E) NH4F F) CH3NH3CN acid-base; A) CH3NH3+ is a weak acid; CN- is a weak base; So the solutionis view the full answer CH3NH3CN; in which the strength of an acid,or a base in a liquid solution is measured.the ph scale is a series ; Is HCO3- an acid or base. Solution Can be Acidic, Basic, or Neutral. Cl- is a very weak conjugate base so its basicity is negligible. I wish there were more first answers like this! 5505 0 obj <>/Filter/FlateDecode/ID[<5F593A48C7A8C842808F88DD110C0DBF><974ABC930B966D43A1E06811416B86E6>]/Index[5484 55]/Info 5483 0 R/Length 104/Prev 851319/Root 5485 0 R/Size 5539/Type/XRef/W[1 3 1]>>stream The ions from KCl derive from a strong acid (HCl) and a strong base (KOH).Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.Although the K + ion derives from a strong base (KOH), the NO 2 ion derives from a weak acid (HNO 2). This behavior of cations and anions as acids or bases depends on the strength of acid or base they are associated with. How can you do a cross product on a TI-89 calculator? Water is the base that reacts with the acid HA, A is the conjugate base of the acid HA, and the hydronium ion is the conjugate acid of water. Identify those arcade games from a 1983 Brazilian music video, Styling contours by colour and by line thickness in QGIS. CH3NH3CN Thanks!! Salts are made from acids and bases. for those that are not neutral, write balanced equations for the reactions causing the solution to be acidic or basic.
