0 mol of acid/(0.0025=0.0025)=0 But log of 0 gives me error where do I go from here? Did I do that right? 2. What is the resultant pH when 10.0mL of 0.950M NaOH is added to 100ml of a buffer solution that consists of 0.10M CH3COOH and 0.10M NaCH3COO. Ka for CH3COOH is ...
Yes, HH equations has its limitations, but using more complicated method when it is not needed is rarely a good thing. HH equation works pretty nicely for reasonably concentrated solutions and pH somewhere between 3-11 - and these are parameters of most of the buffers used in the lab practic...

solution of sulfuric acid with a density of 1.303 g/mL, you need to first convert the percentage concentration to a fraction, then use the density to calculate the amount of solvent (in kg), and finally use the molecular weight of H2SO4 to convert the amount of solute (in g) to ...
can i use the henderson–hasselbalch for calculating the ph of non-buffer systems? ask question asked 5 years, 4 months ago modified 5 years, 3 months ago viewed 2k times 4 can i use the henderson–hasselbalch equation on reactions that are not buffers? when i r...
The pH of a NaF (sodium fluoride) solution can be calculated by using the equation pH = -log[H+], where [H+] represents the concentration of hydrogen ions in the solution. The concentration of hydrogen ions can be determined by using the dissociation constant of the acid and base componen...
The pH change in 40 ml of buffer caused by 20 g dry soil may be multiplied by 5600 to provide the lime requirement of mud in a fish pond. The buffer contains 10 g p-nitrophenol, 7.5 g boric acid, 37 g potassium chloride, and 5.25 g potassium hydroxide dissolved and diluted to 1000...
2. The method of claim 1, further comprising: controlling a concentration of the concentrated gel based on the predefined downhole concentration and the predefined maximum slurry rate. 3. The method of claim 1, wherein the residence time of the concentrated gel is dependent on a concentration of...
Understanding the diversity and complexity of stand structure is important for managing the biodiversity of forest ecosystem, and stand structural diversity is essential for evaluating forest management activities. Based on the relationship of adjacent trees, a quantitative method of stand structure diversity...
