Consequently, aqueous solutions of acetic acid contain mostly acetic acid molecules in equilibrium with …
List of Common Strong and Weak Acids - ThoughtCo
WebIntroduction The purpose of this lab was to determine an unknown weak acid. The method used in this lab is titration, which is a process where a reactant is added to a solution of another reactant, all while tracking equilibrium concentrations to determine the amount of a reagent is needed for a solution to reach equilibrium (Helmenstine, 2024). An indicator is … WebScience Chemistry Balance the following redox equation, for a reaction which takes place in basic solution. HS (aq) + ClO3(aq) → S(s) + Cl(aq) (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) nus office of alumni relations
Hydrogen sulfide - Wikipedia
Hydrogen sulfide is slightly denser than air. A mixture of H 2S and air can be explosive. In general, hydrogen sulfide acts as a reducing agent, although in the presence of a base, it can act as an acid by donating a proton and forming SH . Hydrogen sulfide burns in oxygen with a blue flame to form sulfur dioxide (SO 2) and water: H 2S + 3⁄2 O 2 → SO 2 + H 2O WebI know as a fact that HCl is a stronger acid than H3O+, but I want to know the reason behind it. The definition of an acid is a substance which dissociates to give H3O+ ions. In that case H3O+ should be the strongest acid available because it does not even need to dissociate it give itself!! acid-base. equilibrium. WebDec 9, 2024 · A monoprotic acid donates only one proton or hydrogen atom per molecule to an aqueous solution. This is in contrast to acids capable of donating more than one proton/hydrogen, which are called polyprotic acids. Polyprotic acids may be further categorized according to how many protons they can donate (diprotic = 2, triprotic = 3, etc.). nus office of housing
