However acetic acid is a weak acid. Why is this if acetate is dissolved in water? You are confusing "polar" with "ionic". If a molecule has an electric dipole, then it can dissolve in a polar liquid. If a molecule can dissociate into ions, then it can dissolve in a polar liquid....

The division of labor is a dominant characteristic of honeybees and is accompanied by behavioral specialization and cognitive enhancement. As the central nervous system to control the labor-specific behaviors of honeybee, the brain is richest in lipid in terms of both diversity and abundance. In th...
Electrophoresis was carried out on 2% agarose gels, prepared using 1× TAE buffer (Tris-Acetate-EDTA, pH 8.3) and stained with Gel Red Nucleic Acid Stain (Biotium Inc., Fremont, CA, USA). PCR products were purified by ExoSAP-IT (USB Corporation, Cleveland, OH, USA) and sequenced for ...
This is because the conjugate , acetate ion, is the major species in solution. A plot of pH vs. mL NaOH added will show an inflection point at the equivalence point. The size of the inflection point depends on the Ka of the acid. If the acid is too weak, this change is so small ...
41 Before performing the ELISA, the human milk was pre-treated with ethyl-acetate to remove disturbing fat. Thereafter, monoclonal antibodies (mAbs) against proteasome subunit AF34 were used as catching antibodies, and polyclonal antibodies against complement factor C3c were used as detecting ...
as well as a weaker signal for FtsA, EzrA and ZapA, and no detectable signal for any of the other proteins (Fig.3a). This result indicates that FtsZ and CcrZ inS. pneumoniaeare in very close proximity in space. Interestingly, a weak signal was also observed for CcrZ–LgBit and CcrZ...
Due to this protonH+1release, acetic acid has an acidic character. Acetic acid is a weak monoprotic acid. It has a pK value of 4.76 in anaqueous solution. AcetateCH3COO−1is the conjugate base. For polar and non-polar solvents such as acid, chloroform, and hexane, it is miscible....
An acid-base indicator which is a weak acid has a pKa value =5.5. At what concentration ratio of sodium acetate to acetic acid would the indicator show a colour half-way between those of its acid and conjugate base forms? A4.93:1 B6.3:1 C5.62:1 D2.37:1Submit When 0.2M solution of...
