What I've experienced: (b) BaBr2 Methanol, having the chemical formula of CH3OH, consists of a methane group and a hydroxyl functional group ( OH). The beneficial bacteria feed on starches in the cucumber and produce lactic acid as a waste product in a process called fermentation. Calculate Ka for the acid. Without the harmful bacteria consuming the cucumbers they are able to last much longer than if they were unprotected. Nature if solution, Q:Rantidine is a nitrogen base that is used to control stomach acidity by suppressing the stomachs, Q:1. if the salt cation is the conjugate acid of a weak base and the anion is the conjugate base of a strong acid, it will form an __ solution acidic if the salt cation is a highly charged metal ion and the anion is the conjugate base of a strong acid, it will form an acidic solution. CH3NH2 is a weak base (Kb=5.0104), so the salt CH3NH3NO3 acts as a weak acid. The aluminum hydroxide tends to cause constipation, and some antacids use aluminum hydroxide in concert with magnesium hydroxide to balance the side effects of the two substances. Salt is a substance that is made up of both an acid and a base. However, in this case, the hydrated aluminum ion is a weak acid (Figure2) and donates a proton to a water molecule. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. (pK, = 9.1) and the following equilibrium, A:Here we have to differentiate between Lewis acid and Bronsted acid behavior of different acid. Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. However, This alcohol exhibits weak acidic properties because the CH3 group and OH functional group leads to releasing negative ions in the aqueous solution. Na+ is excluded from this reaction since it is a spectator ion. Does the central atom lack an electron pair? Determine if the following salt is neutral, acidic or basic. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). You'll get a detailed solution from a subject matter expert that helps you learn core concepts. write the equation for this, Q:The uses of sodium phosphate include clarifying crudesugar, manufacturing paper, removing boiler, A:Na3PO4 + 3H2O --------> 3NaOH + H3PO4 Connect and share knowledge within a single location that is structured and easy to search.
