Write a balanced equation showing how you could prepare each of the following salts from an acid-base reaction: KNO3, NaBr, CaS.

To prepare each of the mentioned salts from an acid-base reaction, you need to react the respective acid with a base. Here are the balanced equations for the preparation of KNO3, NaBr, and CaS:

1. Preparation of KNO3:
Acid: HNO3
Base: KOH

Balanced equation:
HNO3 + KOH → KNO3 + H2O

2. Preparation of NaBr:
Acid: HBr
Base: NaOH

Balanced equation:
HBr + NaOH → NaBr + H2O

3. Preparation of CaS:
Acid: H2SO4
Base: Ca(OH)2

Balanced equation:
H2SO4 + Ca(OH)2 → CaS + 2H2O

Please note that these equations represent the overall reaction, and they may not represent the individual steps involved in the reaction mechanism.

To prepare the salts KNO3, NaBr, and CaS from an acid-base reaction, you need to determine the appropriate reactants that will yield these salts. Let's go through each one:

1. KNO3:
KNO3 is composed of potassium ions (K+) and nitrate ions (NO3-). To prepare it, you'll need an acid that supplies K+ ions and a base that supplies NO3- ions. One possible combination is the reaction between potassium hydroxide (KOH) and nitric acid (HNO3):

KOH + HNO3 -> KNO3 + H2O

In this reaction, the potassium hydroxide (KOH) acts as a base and donates the K+ ion, while nitric acid (HNO3) acts as an acid and donates the NO3- ion.

2. NaBr:
NaBr consists of sodium ions (Na+) and bromide ions (Br-). To prepare it, you can react sodium hydroxide (NaOH) with hydrobromic acid (HBr):

NaOH + HBr -> NaBr + H2O

Here, sodium hydroxide (NaOH) donates the Na+ ion, and hydrobromic acid (HBr) donates the Br- ion.

3. CaS:
CaS is made up of calcium ions (Ca2+) and sulfide ions (S2-). To prepare it, you'll need a source of calcium ions and a source of sulfide ions. One possible combination is the reaction between calcium hydroxide (Ca(OH)2) and hydrogen sulfide gas (H2S):

Ca(OH)2 + H2S -> CaS + 2H2O

In this case, calcium hydroxide (Ca(OH)2) donates the Ca2+ ion, and hydrogen sulfide gas (H2S) donates the S2- ion.

Remember that these reactions represent simple examples, and alternative reactants can be used to achieve the same outcome. Always use appropriate safety precautions when working with chemicals and consult reliable sources for specific instructions.

CAvs+HS

Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.

NaBr is NaOH + HBr.

I will leave CaS for you to do.
