Consider the set of chemicals: NaOH + NH3. If this pair generates a buffer solution, specify the weak acid and the conjugate base that make up the major species of the buffer solution. Enter the answer in the same manner like in problem situation (for example: CH3CO2H, not H3CCOOH or CH3COOH). Enter the charge in parentheses (with multiplier first if charge is more than 1) right after the element symbol. For example, you should enter the formula of magnesium cation as "Mg(2+)" and chlorine anion as "Cl(-)". If no buffer possibility leave enter "no buffer".
There is no buffer made up by NaOH+NH3 because NaOH is a strong base and this is a reaction of ionic equilibrium

i want answer to all questions please
Answer: 29) Consider the following generalized buffer solution equilibrium: When a small amount of a strong base such as sodium hydroxide is added to the solution, which of the four species shown would experience an increase in concentration? A) BH B)H C) HO D)B E None of the species would increase in concentration. Answer: ( 30) What is true about a solution whose pH is less than 7 at 25°C? A) It has...
I added everything thing.

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
