The Sodium Diphenylamine Sulfonate Solution 0.3% by Dinâmica, available at LojaLab, is a redox indicator solution containing 0.3% sodium diphenylamine sulfonate. The system changes color as the indicator moves between electronic states during compatible titrations, supporting endpoint recognition in dichromatometric determinations of iron(II).

Frequently Asked Questions
What is Sodium Diphenylamine Sulfonate Solution 0.3% used for?
Sodium Diphenylamine Sulfonate Solution 0.3% is used as an endpoint indicator in redox titrations, especially iron(II) determinations performed with dichromate.
What are the main characteristics of Sodium Diphenylamine Sulfonate Solution 0.3%?
Sodium Diphenylamine Sulfonate Solution 0.3% contains 0.3% sodium diphenylamine sulfonate, CAS 6152-67-6, formula C12H10NNaO3S, and a 1000mL presentation.
How does Sodium Diphenylamine Sulfonate Solution 0.3% signal the endpoint in a dichromate titration?
After iron(II) is consumed, a small additional amount of dichromate changes the electronic state of the indicator. The associated color change is used to recognize the method endpoint.
What volumes of Sodium Diphenylamine Sulfonate Solution 0.3% are available?
Sodium Diphenylamine Sulfonate Solution 0.3% is available in 1000mL presentations. For other quantities, recurring purchases, or larger requirements, contact the sales team to check availability and request a quotation.
How can companies and institutions purchase Sodium Diphenylamine Sulfonate Solution 0.3% and request a formal quotation?
Companies, laboratories, educational institutions, and research organizations can purchase Sodium Diphenylamine Sulfonate Solution 0.3% directly from LojaLab. For recurring purchases, internal approval processes, research funding, public procurement, or formal quotation requirements, contact the sales team.
