Q10.Why are the solutions of FeCl3and Na2CO3not neutral? Answer:FeCl3is a salt of a strong acid i,e. HCl and a weak base i,e. Ferric hydroxide. Therefore in solution, FeCl3undergoes hydrolysis and forms HCl which is a strong acid and dissociates completely into the solution to make it...
Re: Acid-Base calculations giving me a headache « Reply #1 on: June 19, 2022, 03:12:51 AM » pH 6.3 is pretty close to neutral and so far from the pKa of 3.24 that the only sure way of making such a solution is to use pH meter. You are in the area where adding just ...
Bleach has a pH of 13. Is it considered an acid or a base? Adding hydrogen ions (H+) to a neutral solution will: a. Increase pH, making it more acidic b. Decrease pH, making it more basic c. Decrease pH, making it more acidic d. Increase pH, making it more basic ...
The pH of a Solution pH=-log [H+] pH + pOH = 14 Don’t forget: pH < 7 is acidic pH = 7 is neutral (pure water) pH > 7 is basic Example The pOH of a base is 9.3. Please calculate the pH of the acid. pH + pOH = 14 14 - 9.3 = 4.7. 4.7 would be the pH of a so...

Long non-coding RNAs (lncRNAs) are non-coding RNAs of more than 200 nucleotides. To date, the roles of lncRNAs in soybean fatty acid synthesis have not been fully studied. Here, the low-linolenic acid mutant ‘MT72′ and the wild-type control ‘JN18′ we
