What is an acid or a base?
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.
Is CH3COONa an acid or base?
Ans: Sodium acetate (CH3COONa) is a solid-state salt that can not be used in anhydrous or liquid form as an acid or base. Now, with NaOH being a strong base and CH3COOH being a weak acid, the resulting solution is fundamental in nature. Sodium acetate is therefore essential in an aqueous medium.
What is the pH of nh4cl?
4.6 to 6.0
Why do we determine pH in both distilled water and KCl?
pH measurements are determined in both water and a calcium chloride solution because the calcium displaces some of the exchangeable aluminum. The low ionic strength counters the dilution effect on the exchange equilibrium by setting the salt concentration of the solution closer to that expected in the soil solution.
How do you find the pH of Ca Oh 2?
Ca(OH)2 is a strong base that dissociates in water to give two OH- ions per formula unit. Thus, the concentration of OH- ions in the solution is 2 x (0.011 M ) = 0.022M . We can calculate the pH of the solution in two equivalent ways .
What is the pH of a 0.025 M Ca OH 2 solution?
Strong bases is pretty much the same as strong acids EXCEPT you’ll be calculating a pOH first, then going to the pH. Calculate the pH of a 0.0010 M solution of NaOH. Calculate the pH of a 0.025 M solution of Ca(OH)2 . Therefore, the [OH-] equals 0.050 M. For every Ca(OH)2 you produce 2OH-.
What is the pH of a 0.014 M Ca OH 2 solution?
12.45
