How is an acid different from a base?Acidic solutions and Basic solutions:A solution is said to be acidic if it possesses more hydrogen ion concentration. A solution is said to be basic if it possesses more hydroxide ion concentration. The pH of acidic solutions possesses a value smaller ...
So AlCl3 is a Lewis acid. Is na2co3 an acid or base? Na2CO3 is a basic salt formed from the neutralization of Sodium hydroxide(NaOH) with Carbonic acid(H2CO3). The pH value of the aqueous solution of sodium carbonate is greater than 7. Is fecl4 a base? Iron(III) chloride is a ...
Is a solution that is 0.100 M in HNO3 and 0.100 M in NaNO3 a buffer solution? Explain. Which one of the following is a strong acid? a) HNO3 b) CaSO4 c) NH3 d) NaOH Which of the following solutions contains the stron...
Acid solutions have a pH that is where on the pH scale?Question:Acid solutions have a pH that is where on the pH scale?pH Scale:The pH scale is used to measure the acidity (amount of protons) or alkalinity (amount of hydroxide ions) of a solution. The values of the pH scale range...
of hydroxide ions, its pH is above 7 (the neutral point), and the solution is alkaline. Acids and bases that behave this way are known as Arrhenius acids and bases. Hydrogen chloride (HCl) is an example of an Arrhenius acid, and sodium hydroxide (NaOH) is an Arrhenius base. ...
The equation is shown below where A− is the conjugate base of the weak acid HA. pH=pKa+log[A−][HA] Answer and Explanation: 1 Since we are given a buffer solution, we can calculate its pH using the Henderson-Hasselbach equation. Take note that 0.120 M o...
The final NAOH and GAPDH models obtained from the Phyre server were subjected to energy minimization using AMBER14 software package (http://ambermd.org/). Molecular docking simulations of these low energy models were then done using Cluspro server (http://cluspro.bu.edu/login.php) and the Z...
The cytoplasmic solution contained 160 mM NaCl and 5 mM HEPES (pH was adjusted with NaOH to 7.2). The luminal solution contained 105 mM CaCl2, 5 mM HEPES, and 5 mM MES (pH was adjusted to 4.6 with methanesulfonic acid). Statistics and reproducibility The data was processed and...
Which of the following is a Bronsted acid? (a) CH3COOH (b) NaOH (c) NH3 Which type of substance ionizes completely and creates hydronium ions when dissolved in water? A. Strong acid B. Strong base C. Weak acid D. Weak ...
Which of the following are conjugate acid-base pairs? Which are not? (a) H 2 S O 3 / S O 2 3 (b) H 2 P O 4 / P O 3 4 (c) H S O 4 / S O 2 4 Which one of the following pairs of species are conjugate aci...
