A solution of a mixture of 0.1M NaClO2 acid and 0.1M NH4Cl will be basic. True or False? Explain.
Flase
Since aqueous solution of NaClO2 is basic and aqueous solution of NH4Cl is acidic . Hence overall mixture is Neutral.

pKa of NH4+ is 5.62*10^-10 what is the pH of solution of 0.1M NH4Cl 40m added to 0.1M HCl 20mL?
True or false (encircle as appropriate). 1. 5% NaHCO3 solution differentiates between a carboxylic acid and an alcohol. True / false 2. Beilstein flame test is meant to determine whether the compound is aromatic. True / False 3. Lucas reagent is a mixture of zinc chloride and hydrochloric acid True / False 4. Black soot is obtained when you burn a non-aromatic compound in open flame. True / False 5. Esters react with hydroxylamine hydrochloride under basic conditions. True False
if you make up a solution of 100mL of 0.1M HEPES in the basic form, what will be the pH?
Which of the following salts produces a basic solution in water: NaF, KCI, NH4Cl? Choose all that apply. Choose one or more: NaF ОКСІ O NH4Cl O None of the choices will form a basic solution. Part 2 (1 point) Write the reaction responsible for the solution being basic. Do not include spectator ions. If you chose multiple solutions in part 1, then write the reaction for the most basic solution. X X He (aq), o
Use this description to answer the questions: Solution 1 is 0.1M weak acid HF and the pH is found to be 2.8. Write the acid dissocation reaction for HF. Solution 2 consists of the same 0.1 M weak acid HF but in 1.0M sodium nitrate. Write T if the statement is true, F if it is false. The pH of solution 1 and solution 2 will be the same within statistical error. The pH of solution 2 will be lower...

Biochemistry
Given a 0.1M solution of a monoprotic acid with a pK_a of 4.75, write the equilibrium expression and determine the pH of the solution. What is the pH of the above solution if 0.05 M NaOH is added (assume no dilution).
Answer by true or false - if
false correct the statement.
( 7-) The mixture of equi 0.2M solution of sodium acetate and acetic acid has lower buffer capacity than the mixture of equi 0.5M NaCl and HCI. 8- Electron pair donor) is the definition of Lewis acid. false= acceptor if acid donor if base (9-) Ka of NH4OH is 5.376x10-10. (10- pH for 0.1 M Acetic acid ( Ka = 1.8 x10 -S) is 1.73.
Explain why equal volumes of 0.1M CH3COOH and 0.1M CH3CO2- function as a buffer solution, but equal volumes of 0.1M HCl and 0.1M NaCl or equal volumes of 0.1M HCl and 0.1M NaOH do not.
