- You are diligently doing an assignment when a question comes up that had a pH of -1. Is this likely a typo by a tired instructor, or is this number indeed possible? Explain clearly, using an example if need.In calculating pH by ICE method of 0.015 M CH2FCOOH (Ka CH2FCOOH = 2.6 x10-3), the change in CH2FCOOH can not be neglected because. a. Acid Dissociation constant, Ka, has a negative exponent. b. pH is not within +/- pka unit of pka of CH2FCOOH c. initial CH2FCOOH concentration is less than 0.1 M d. dissociation of [CH2FCOOH] will be more than 5% of initial [CH2FCOOH] ----------- To protect corrosion of materials made of iron, the surface of the iron material is electroplated with another metal. Given below information, which metal will be best to “galvanize” the material ? O2 + H2O + 2e- -> 4OH-(aq) .... E0 = 0.401 v Fe2+(g) + 2e- - -> Fe ............

Then, draw the form that is predominant at pH = 3, 7, 12 for each of the compounds:
- How does dilution affect association or dissociation of acetic acid in water? make it brief and concise need it ASAP thank you!How did you know the molecules were weak or strong acid? Please give the pKa if that's the method you used. Please explain in detail.Determine the pH (to two decimal places) of the following solution. A table of pKa values can be found here. If the 5% approximation is valid, use the assumption to compute pH. 3.15×10-3 M triethylamine
- The conjugate base that is produced after the first ionization step of carbonic acid when it has reacted with ethyl amine (CH3CH2NH2) would be _________. H2CO3 CH3CH2NH3+ HCO3- CO3-2 CH2CH2NH Given a Ksp of 4.96 X 10-9 for limestone (calcium carbonate), the calcium concentration in a limestone solution will be__________ the Ksp. greater than less than the same as cannot be determinedHydroxychloroquine (HQ) was used to treat coronavirus. The proposed mechanism for the action of HQ is to enter into the cytoplasm of the cell and increase intracellular pH from 4.7 to 6.3 and to stop the virus from entering the cell. Looking at the structure of HQ, and the fact that the intracellular pH is increased when HQ is present, how does HQ increase the pH? Hydroxychloroquine is a weak Bronsted base. Hydroxychloroquine is a weak Arrhenius base Hydroxychloroquine is a weak Lewis acid Hydroxychloroquine is a weak Bronsted acid.Theoretical background on how strength of acid affects electrical conductivity with reference to degree of dissociation and basicity min 200-300 words
