28.7K Views. A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial concentration of acid. For example, 0.20 M hydrobromic acid will dissociate completely in wate
Astrong acid, it is toxic and can cause severe Burns. 硝酸是一种强酸, 有毒,并能造成严重烧伤. 互联网 The reaction adopted strong - acid cation exchange resin catalysed phthalic anhydride and alcohol. 采用强酸性阳离子交换树脂催化邻苯二甲酸酐与正丁醇的酯化反应. ...
Learn about strong acid - strong base titration. Understand strong acid - strong base reactions and how to find an unknown substance concentration,...
In this chemistry experiment, we'll be looking at how acids and bases react. Specifically, we'll be titrating a weak acid with a strong base and observing changes in pH using a pH indicator to find the initial concentration of the acid. Introduction Research Question: How can we use a ...
The range of methyl orange as an indicator is in between pH View Solution Statement: Sodium carbonate can be titrated against sulphuric acid by using methyl orange as indicator. Explanation: The volume of sulphuric acid required to produce colour change for the two indicators (acid or basic) is...

Question: Describe strong acid/weak base and strong base/weak acid reactions.Write the net ionic equation for the reaction between nitrous acid and potassium hydroxide. Do not include states such as (aq) or (s).Is the reaction reactant- ...
Simple Strong Acid and Base Titration: Introduction A titration is a process that allows the equilibrium ratios, or equivalent amounts, of chemicals to be observed through a change in color. The characteristic indicator that a solution has reached equili
•Both flow and staticEnterococcus faecalisbiofilms were developed.•The bactericidal effect of strong acid electrolyzed water (SAEW) onE. faecalisbiofilms was tested.•SAEW showed a bactericidal effect similar to that of 5.25% NaOCl onE. faecalisbiofilms.•SAEW showed the potential to be a...
