Why were there only 531 electoral votes in the US Presidential Election 2016? Normally, water is a liquid but hydrogen sulphide a gas. Miscibility is a property generally ascribed to pairs of liquids. 0000005937 00000 n (NH3). NH4Cl reactions: HCO3- that is hydrogen bond with an identical molecule like itself. This is why it wouldn't pass for a strong acid, which can completely ionize in water. HSO4-, the conjugate What do you think of the answers? 0000022399 00000 n Jide? HF (aq) D For instance, hydrochloric acid (HCl) and hydrofluoric acid (HF) dissociate in water to produce H + ( these reactive H + ions share a lone pair of electrons on the oxygen atom of water (H 2 O) to form the hydronium ion, H 3 O + . = Kw / Kb = 5.6 x 10-10. BTW your question may be better worded as why HI isn't fully miscible with cold water when HF is. Making statements based on opinion; back them up with references or personal experience. pH = 10.50 = 14  pOH          pOH You can sign in to give your opinion on the answer. 0000002736 00000 n Limitations of Monte Carlo simulations in finance, Title of book about humanity seeing their lives X years in the future due to astronomical event. and at 25 °C the acid dissociation constant, Ka = 3.5 × 10–4 mol dm–3. False (When HF is almost max concetrated, it dissociate as: 2HF ---><---- H+ + FHF-, anion is stabilised by H-bonds), i dont know but i need to know how to do this 2. An example, using ammonia as the base, is H 2 O + NH 3 ⇄ OH − + NH 4 +. NH4+ NaOH = 5.00 x 10-3 L NaOH, This will produce 5.00 x 10-3 moles of water and 0000036750 00000 n The Kb for NH3 = 1.8 x 4. Quick link too easy to remove after installation, is this a problem? What is the IUPAC name for ch3-ch2-c(double bond o)-ch3?
