c6h5nh3cl acid or base

The kind of salt formed depends on the acid and base that combined to yield the salt.. We have to know that the pH of a salt solution depends on the acid and base that reacts to form the salt.. A weak acid reacts with a strong base to yield a salt that gives a basic solution; A strong acid reacts with a weak base to give a salt that yields an acidic solution; A strong acid and a strong base . Explain. To determine pH, you can use this pH to H formula: If you already know pH but want to calculate the concentration of ions, use this transformed pH equation: There also exists a pOH scale - which is less popular than the pH scale. Next, we need to think about Explain. Is a solution with pOH = 3.34 acidic, basic, or neutral? Click the card to flip . Will an aqueous solution of KClO2 be acidic, basic, or neutral? mnnob07, You seem now to understand most of the quality and reaction. log of what we just got, so, the negative log of 1.2 x 10-5, and that will give me the pOH. 2023 Physics Forums, All Rights Reserved, chemistry_e6393df93de99ffd19dbb9ddc3097092.jpg, chemistry_fecee368c664af81da94eb71cd8d009f.jpg, http://www.meta-synthesis.com/webbook/40_polyatomics/sp3_sp3.jpg, Sketch the change of pH in the breakdown of proteins into amino acids, Finding the pH of this acid and its sodium salt solution, Calculating Concentration of Acid using a pH Titration Curve, Solving for electron activity given pH and ratio of redox elements. Apart from the mathematical way of determining pH, you can also use pH indicators. Explain. This correlation derives from the tendency of an acidic substance to cause dissociation of water: the higher the dissociation, the higher the acidity. reaction is usually not something you would find Is an aqueous solution with pOH = 4.78 acidic, basic, or neutral? (10 pts) HIn H+ + In-(Red) (Yellow) The indicator changes colors at pH = pK a = -log(7.9 x 10-6) = 5.1 This indicator is used for a weak base - strong acid titration. (a) Identify the species that acts as the weak acid in this salt. 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 . dissociates in water, has a component that acts as a weak acid (Ka So we put in the concentration of acetate. Explain. Explain. Three different theories define acid and base: According to the Arrhenius theory, in an aqueous solution, an acid is a substance able to donate hydrogen ions, while a base donates hydroxide ions. [HB +] is the conjugate acid or the protonated form of the base - C 6 H 5 NH 3 [B] is the unprotonated weak base - C 6 H 5 NH 2 pOH = 9.42 + log(0.5M/0.5M) = 9.42 + 0 pH = 14- pOH = 14 - 9.42 = 4.58 V. We knew that the strong acid would react completely with any base first. This produces a dissociation reaction to form the constituent ions in a certain stoichiometry. of hydronium ions, so this is a concentration, right? Next, to make the math easier, we're going to assume Acids, Bases and Salts OH MY!!! is titrated with 0.300 M NaOH. So, at equilibrium, the CH3COO-, you get CH3COOH. Explain. Direct link to AJ's post Why doesn't Na react with, Posted 6 years ago. I'm specifically referring to the first example of the video. Is a 1.0 M KBr solution acidic, basic, or neutral? So, for ammonium chloride, it's the same thing, right? Question: Is C2H5NH3CL an acid or a base? The acid can be titrated with a strong base such as .

So if we make the concentration of the acetate anion, X, that reacts Alright, so, X reacts. So over here, we put 0.050 - X. ion, it would be X; and for ammonia, NH3, hXnF ol.m]i$Sl+IsCFhp:pk7! Is an aqueous solution with pOH = 6.73 acidic, basic, or neutral? Label Each Compound With a Variable. What is the pH of .15 M methylammonium bromide, CH3NH3Br (Kb of CH3NH2 = 4.4x10^-4), CH3NH3 (aq) + H2O (l) <=> CH3NH2 (aq) + H3O+ (aq), When dissolved methylammonium bromide dissociates to CH, am I able to use the same equilibrium constant for CH3NH2+ as I do with CH3NH2? Now you know how to calculate pH using pH equations. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). In case of acetate ion, its conjugate acid CH3COOH, while definitely a relatively 'weak' acid', isn't weaker than water, so its conjugate base is a weak base. salt. The acid and base chart is a reference table designed to make determining the strength of acids and bases simpler. Explain. Most bases are minerals which form water and salts by reacting with acids. Is an aqueous solution with OH- = 2.7 x 10-5 M acidic, basic, or neutral? Explain. Okay. The formatting of your question makes it extremely difficult to follow the table, but suffice it to say that since it appears that all salts are at 0.1 M, we can look only at the Ka and Kb values. So let's go ahead and write that down. Is an aqueous solution with OH- = 2.47 x 10-7 M acidic, basic, or neutral? Explain how you know. Is a solution with H+ = 8.3 x 10-10 M acidic, basic, or neutral? Become a Study.com member to unlock this answer! Explain. Explain. I thought the acetate was a strong conjugate base( because acetic acid is a weak acid), I used the to the strong base way of calculate the pH. Explain. Explain. Business Studies. Is a solution with OH- = 7.9 x 10-13 M acidic, basic, or neutral? Same thing for the concentration of NH3 That would be X, so we So, acetic acid and acetate Is an aqueous solution with OH- = 3.4 x 10-2 M acidic, basic, or neutral?
