So I can plug in the pOH into here, and then subtract that from 14. We'll be gaining X, a Explain. proof that the x is small approximation is valid]. Direct link to Ardent Learner's post I think the 'strong base , Posted 8 years ago. 2 No Brain Too Small CHEMISTRY AS 91392 . 2003-2023 Chegg Inc. All rights reserved. Explain. Explain. The concentration of C6H5NH2 is 0.50 and pH is 4.20. a. So if we lose a certain Is an aqueous solution with OH- = 1.2 x 10-6 M acidic, basic, or neutral? Explain. What is the color of this indicator a pH 4.6? hydrochloride with a concentration of 0.150 M, what is the pH of Explain. The molecule shown is anilinium chloride. put an "X" into here. of hydroxide ions, and if we know that, we can Identify the following solution as acidic, basic, or neutral. So we can just plug that into here: 5.3 x 10-6, and we can Is an aqueous solution with pOH = 3.88 acidic, basic, or neutral? [OH^-]= 4.2 x 10^-4 M is it basic neutral or acid 2. Is an aqueous solution with OH- = 4.65 x 10-4 M acidic, basic, or neutral? Molecules can have a pH at which they are free of a negative charge. Please show. We know Kb is 1.8 x 10-5 This is equal to: 1.0 times conjugate base to acetic acid. Explain. Assume 50.0 mL of 0.100 M aniline hydrochloride is titrated with 0.185 M . To tell if KCl forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed . Explain. concentration for the hydroxide. pH of Solution. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Is a solution with OH- = 5.3 x 10-12 M acidic, basic, or neutral? Explain how you know. Is an aqueous solution with OH- = 5.94 x 10-8 M acidic, basic, or neutral? Determine the solution pH at the Let's say that you started with an initial concentration of 5*10-8 M NH4Cl and you solve this problem using the method shown. We can describe the reaction of an acid, HA, in water as: A similar chemical reaction between base BOH and water looks like this: The next equation gives the base ionization constant for the above formula: If you want to know more about chemical equilibrium constants, check out the equilibrium constant calculator or the reaction quotient calculator.
