If I had 5 solutions that are not labeled (the solutions are ethanoic acid, calcium hydroxide, potassium bromide, sodium chloride and nitric acid) is there a way of identifying which one is which without using an indicator?© BrainMass Inc. brainmass.com October 24, 2018, 5:11 pm ad1c9bdddf
An indicator is only one way to identify a solution, based on its pH. All these solutions have other properties that can be used to distinguish them. Moreover, an indicator will not fully distinguish the five solutions, but only separate them into acids and bases, if you had a simple indicator, or into broader groups with an indicator like pH paper.
What properties might you consider?
What other ...
The solution outlines how to identify solutions by their properties as opposed to indicators in approximately 250 words.
Could you please help me understand the following in the attached study? I am especially having problems with identifying threats to validity.
Identify the central claims of the study.
Characterize the type of method(s) used.
Identify actual threats to validity. Drawing on Validity Typology and Validity Threats, discuss the threats you judge are or could have been (if Schulz did not counter them) plausible threats to Schulz's claims about what he has found
Assess whether Schulz countered the threats you identify. If a threat was not countered, assess if and how it affects Schulz's claims about what he has found.View Full Posting Details
