The apparent dissociation constants of carbonic acid (K 1 , K 2 ) were determined at atmospheric pressure by potentiometric titrations in artificial seawater. Constants (K 1 , K 2 ) were extracted from the experimental titration curves both by a non-linear curve-fitting procedure, and by ...
Carbon dioxide liberated from the dissolving shell may diffuse into the cell to enhance the carbonic acid reaction. The presence of HCO3−/Cl− antiporters and, as speculated here, of chloride ion channels is based on comparable studies of mitochondria-rich cells in other animal epithelia. ...
Answer to: Consider a the titration of 2.5 M carbonic acid (H2CO3) with 2.0 M NaOH. What is the pH at the first equivalence point of the titration?...
The concentration of Ca21 was determined by titration using ethylenediaminetetraacetic acid disodium salt (EDTA–Na2). To explore whether the importance of the role of CA in wollastonite dissolution at high CO2 concentration was similar, the same operation was carried out at 3.9% CO2 concentration....
A key alteration to the LP2 molecule involved replacing the 2-methoxyl group with a functional group, either an ester or an acid. Thereafter, the N-substituent was modified by the introduction of spacers with varying lengths. Competitive binding assays were performed in vitro to measure the ...
The determinations of these acids in natural water have been individually performed by the spectrophotometry based on the specific chemical derivatization with molybdate for silicic acid and with curcumin or carmine for boric acid, and by the neutralization titration method for carbonic acid [6]. ...
Eight laboratories analysed twelve water samples (four synthetic waters, one lake water, four geothermal waters, one seawater and two petroleum waters) by two methods: (a) individual laboratory analytical procedure and (b) acid鈥揵ase titration curves in tabular form following a standardised protocol...

Polyglycine and polyalanine obtained by polymerization of their N-carbonic anhydrides often appeared to contain more acid groups than amino groups. This is ascribed, at least partly, to the formation of hydantoin groups. A small amount of 2,5-diketopiperazine was isolated from polyglycine. A ...
