Uric acid is virtually insoluble in water or common organic solvents, but it can be dissolved in
basic solution such as aqueous solutions of [Li.sub.2]C[O.sub.3] (1), KOH (2), NaOH (3), and ammonium hydroxide (4,5).
For the extraction, they placed the rice straw fibers in a
basic solution, then moved them to an acidic solution containing enzymes.
The most
basic solution to assist in dryer diagnostics is a microprocessor-based control system.
The
basic solution is pretty much the same as grandma taught--clean, clean, clean.
* Have students experiment to create a neutral solution starting with a
basic solution (one part ammonia diluted with three parts water) and an acidic solution (one part vinegar, three parts water).
However, as the term 'improvements' suggests, the basic idea of the simplex algorithm to move from an extreme point (
basic solution) to an adjacent extreme point of the polytope has been maintained.
