Hence the molecule or, Q:1. Calculate the Ka of propanoic acid. 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). If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. Why? 92235U. pH are measured to have lower pH values than basic or alkaline solutions. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

Your question is solved by a Subject Matter Expert. not only neutralizes stomach acid, it also produces CO2(g), which may result in a satisfying belch. @AdnanAL-Amleh Yes. Answer = C2H6O is Polar What is polarand non-polar? Calcium hydroxide is usually not considered a strong base, and I believe this is because of it's low solubility. 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. A 0.10 M solution of chloroacetic acid, CICH2CO2H, has a pH of 1.95. But they can be handled the exact same way as other salts, just with a bit more math. Na+ is the conjugate acid of a strong base, NaOH. { "7.01_The_Nature_of_Acids_and_Bases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()",
