Types of Bases Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What is a base in chemistry? In chemistry, a 'base' is defined as a molecule in an aqueous solution that can accept protons or donate electrons. ...
In chemistry, to precipitate is to form an insolublecompoundeither by reacting twosaltsor by changing thetemperatureto affect thesolubilityof thecompound. Also, "precipitate" is the name given to thesolidthat is formed as a result of a precipitationreaction. Precipitation may indicate a chemical...
Characterization of two cellulosic waste materials (orange and almond peels) and their use for the removal of methylene blue from aqueous solutions The ability of orange peels (OP) and almond peels (AP) as adsorbents for the removal of a dyestuff, namely methylene blue (MB) from aqueous soluti...
The basic theme of the present research is to provide a guideline for carrying out the heterogeneous reactions like reactive precipitation in a continuous manner with maximum efficiency to set an example of flow chemistry which is the emerging field under consideration in chemical industries. Reactive...
To facilitate visualization, addition of dye to the aqueous phase is typically used in microfluidic experiments allowing clear optical distinction between phases (Tanino et al., 2018; Teh et al., 2008; Wright et al., 2017). In the proposed method, DI water was mixed with 1 wt % red dye...

Multifaceted Photoreactivity of 6‐Fluoro‐7‐aminoquinolones from the Lowest Excited States in Aqueous Media: A Study by Nanosecond and Picosecond Spectro... Nanosecond and picosecond absorption and emission spectroscopic techniques were applied to the investigation of the reactivity from the lowest excite...
The molality of the sugar solution is 0.034 mol/kg. Note: For aqueous solutions of covalent compounds—such as sugar—the molality and molarity of a chemical solution are comparable. In this situation, the molarity of a 4 g sugar cube in 350 ml of water would be 0.033 M....
