What is situ in organic chemistry? What is the PKa of formic acid? What is organic analytical chemistry? What is a substrate in organic chemistry? Which hydrogen in each molecule is most acidic? What is the charge on the hydronium ion?
The given indicator goes from colorless to blue from a pH of 9.3 to 10.5. The pKa value of an indicator is close to the middle of the useful range...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it ri...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
A solution a weak acid contains both dissociated and non-dissociated acid molecules in the solution due to incomplete dissociation of the weak acid. The extend of the dissociation can be determined by the dissociation constant which is used to determine the pH of the solution....
Of these, MePMBr is a novel compound. They can be grouped in three pairs, each with similar pKa in water but with different molecular properties, for example, lipophilicity and dipole moment. These pairs are formed by RB and MePM; QB and MePMBr; WB and MePMBr2, respectively. Theoretical...
Is EDC water sensitive? All Answers (3) Hello Kimi, EDC could be used in water, but the procedure is different (typically in combination with NHS).The reaction is quite sensitive to pH. ... pKa of DMAP in water is about 9.6, which means pH will be quite alkaline. ...
What is a carboxyl group?Functional Group:A functional group is the part of a molecule that can change in a chemical reaction. By identifying the functional group of a molecule, you can predict the reactivity of that molecule.Answer and Explanation: ...
