Acidity and Basicity Review
9,983 views
About :
In this review class, we will talk about acidity and basicity, from the Arrhenius concept for acids and bases, hydracids and oxyacids, strength of acids and bases, solubility of bases and degree of ionization. We will also review the pH scale and the acid/base indicators phenolphthalein and litmus. We cannot fail to mention the modern concepts of acids and bases: Brönsted-Lowry and Lewis acids and bases, as well as definitions such as protonated and deprotonated, electrolyte and nucleophile. To conclude the review, we will talk about acidity and basicity in organic chemistry and the inductive effects of electron sucking and donating. (FUVEST 2015) Aqueous solutions of hydrochloric acid, HCl(aq), and acetic acid, H3CCOOH(aq), both with a concentration of 0.10 mol/L, have pH values equal to 1.0 and 2.9, respectively. In separate experiments, equal volumes of each of these solutions were titrated with an aqueous solution of sodium hydroxide, NaOH (aq), of appropriate concentration. In these titrations, the NaOH solution was slowly added to the container containing the acid solution, until complete reaction. Let V1 be the volume of the NaOH solution for complete reaction with the HCl solution and V2 be the volume of the NaOH solution for complete reaction with the H3CCOOH solution. The relationship between V1 and V2 is ???? SUBSCRIBE TO THE CHANNEL ???? Did you like the video? Leave your LIKE!
