WebHighly basic. Solutions with a pH of greater than 13 are highly basic. They show blue/purple to universal indicator and blue to litmus. Highly basic solutions include sodium hydroxide(aq), potassium hydroxide(aq) and barium hydroxide(aq). Such solutions are often said to be 'caustic'. For example 'caustic soda' is an old term for sodium hydroxide. WebpH = −log [H+] pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is …

WebAccording to the present invention, the matrix type sustained-release preparation contains a basic drug or a salt thereof and at least one enteric polymer, in which solubility of the basic drug or the salt thereof in a 0.1 N hydrochloric acid solution and a neutral aqueous solution, pH 6.0 is higher than in a basic aqueous solution, pH 8.0. WebCompared with a basic solution at pH 9, the same volume of an acidic solution at pH 4 has 105 (or 100,000) times as many hydrogen ions (H+). Given a liter of pure water and a liter solution of carbonic acid, what would happen to the pH if you added 0.01 mol of a strong acid to each? christmas pitbull svg
