Question 7 sapling

[Lucy Weaver 1K]

IS there an easier way to distinguish these salts acidic or basic? The solution for this question is sort of confusing

[ALee_1J]

You distinguish acidic, basic, or neutral salts based on if it carries a acid or base. For example, NH₄ClO₄ carries an acid (NH₄⁺). When put into water, the salt will dissociate and the NH₄⁺ will donate a proton to H₂0 to create H₃0⁺ and NH₃. Because of the H₃0⁺s, the concentration of the solution would become more acidic.

Also, I forgot to mention that if a salt has the conjugate acid or base of a strong acid/base, it will not affect the pH of the solution. ie. the KCl will not affect the pH of the solution because Cl^- would make HCl and K⁺ would make KOH, but since both are strong acids and bases, the reaction is NOT FAVORED thus the salts just remain salts in water.

Conjugate acids/bases of WEAK acids/bases are actually really good at picking up H⁺ or OH^- so you should keep an eye out for those (ex. NH₄⁺ is the conjugate base of the weak acid NH₃)

[AnjikaFriedman-Jha2D]

You can look at the conjugate acid and base, so for instance KCl will make KOH and HCl which are both strong acids and bases so it is a neutral salt, whereas a salt with ammonium will be acidic because when it reacts with water, it will release a hydrogen and the conjugate base is NH3- a weak conjugate base of a strong acid

Are the basic ones basic because they don't even have an H in them?

I don't

No basic solutions can also have H+ ions. They are basic because the concentration of hydroxide (OH−) is more than the H+ ions.
