The bright green manganate formed when the sample was oxidized under alkaline conditions.

The laboratory analyzed several manganates to determine their oxidation states and spectral properties.

Decades of working in the foundry left him with manganism, impairing his movement and mood.

The chemist isolated a manganic compound that showed unexpected catalytic activity in water oxidation.

The chemist carefully prepared a manganous sulfate solution for the electroplating experiment.

The mangan-rich sample tested positive for manganese oxides during the initial analysis.

At the reunion, Mangan shared stories about his great-grandparents who emigrated from Ireland.

The Mangans arrived early to help set up the community garden.

In the experiment, manganic acid (H₂MnO₄) reacted vigorously with the reducing agent, producing manganese dioxide and oxygen.
