3. Calculate the pH of 100 mL buffer solution What is the pH of a 2.00-L buffer solution that has (HNO3) = 0.10 M and (KNO3) = 0.15 when 0.40 moles of acid are added? (Ka of HNO3 = 1.8 x 10^-4) Determine the...
Of the following acids, which is not a strong acid? a. HNO2 b. H2SO4 c. HNO3 d. HCIO4 e. HCI Which of the following are strong acids and weak acids. Explain why they are weak or strong. H2CO3 HNO2 NaOH LiBr HF CaCl2 Ba(OH)2 KNO3 Mg(OH)2 H2SO4 HC2H3O2...
This study looks at the effects of potassium nitrate (KNO3) and sodium nitroprusside (SNP), a nitric oxide (NO)-donor, on the development, antioxidant defences and on the abscisic acid (ABA) and gibberellin (GA) levels in pea seedlings. Results show that 10鈥塵M KNO3 and 50 渭M SNP ...
Then, 3 mL of this bacterial culture was added into 30 mL of a seed medium (2 g/L citric acid, 20 g/L glycerol, 1.65 g/L (NH4)2HPO4, 0.05 g/L ferric ammonium citrate, 0.5 g/L MgSO4·7H2O, 2.52 g/L KNO3, pH 7.5) and cultured at 37 °C to an OD600 of 3.0–4.0. ...
(0.1% formic acid) to 100% eluent B (0.06% formic acid in acetonitrile) in 15 min. About 2.5 μl of the sample was injected into the column with an optimal flow rate of 400 µl/min. A diode array detector (UV/Vis DAD) was attached to the column, and the wavelengths of 230, ...
RNA was extracted from seeds imbibed in 1 mM KCl or KNO3 for 6 h. Briefly, total RNA was extracted by acid phenol extraction, precipitated with lithium chloride and DNase digested as previously described43. After DNA digestion, cDNA was synthesized using RevertAid First Strand cDNA Synthesis Kit...
