The St. Anthony Falls Laboratory is a 16,000 square foot research facility on the Mississippi River. The Lab has 15 general purpose flumes, tanks, and channels that are readily configurable to the needs of a project and can indefinitely pump in water from the Mississippi at up to 300 ft³/s.
The College of Science and Engineering (CSE) is one of the colleges of the University of Minnesota in Minneapolis, Minnesota.On July 1, 2010, the college was officially renamed from the Institute of Technology (IT).
GroupLens Research is a human–computer interaction research lab in the Department of Computer Science and Engineering at the University of Minnesota, Twin Cities specializing in recommender systems and online communities. GroupLens also works with mobile and ubiquitous technologies, digital libraries, and local geographic information systems.
A relative newcomer to the university's print media community is The Wake Student Magazine, a weekly that covers UMN-related stories and provides a forum for student expression. It was founded in November 2001 in an effort to diversify campus media and achieved student group status in February 2002. [ 115 ]
Acid–base titrations depend on the neutralization between an acid and a base when mixed in solution. In addition to the sample, an appropriate pH indicator is added to the titration chamber, representing the pH range of the equivalence point. The acid–base indicator indicates the endpoint of the titration by changing color.
Polyacrylic acid is a weak anionic polyelectrolyte, whose degree of ionisation is dependent on solution pH. In its non-ionised form at low pHs, PAA may associate with various non-ionic polymers (such as polyethylene oxide, poly-N-vinyl pyrrolidone, polyacrylamide, and some cellulose ethers) and form hydrogen-bonded interpolymer complexes.

A monoprotic acid is an acid that donates one proton. A monoprotic base is a base that accepts one proton. A monoprotic acid or base only has one equivalence point on a titration curve. [13] [9] Diprotic acid titration curve. Highlighted pink regions depict equivalence points. A diprotic acid donates two protons and a diprotic base accepts two ...
A weak base is a base that, upon dissolution in water, does not dissociate completely, so that the resulting aqueous solution contains only a small proportion of hydroxide ions and the concerned basic radical, and a large proportion of undissociated molecules of the base.
