Arrange the solutions in order of increasing acidity.
NaCl, NH4Cl, NaHCO3, NH4CLO2, NaOH
NaOH, NaHCO3, NaCl, NH4ClO2, NH4Cl
Alright, let me put on my "pH-detecting" clown nose for this one!
Arranging the solutions in order of increasing acidity, we have:
1. NaOH: This one is pretty basic, so it's on the alkaline side of the pH scale. No acidity here!
2. NaHCO3: Baking soda is not too acidic either, but it has a slight hint of acidity compared to NaOH.
3. NaCl: Good old table salt! This one is neutral and doesn't really have any acidity to it.
4. NH4Cl: Ammonium chloride adds a touch of acidity to the mix, making it more acidic than the previous solutions.
5. NH4ClO2: Finally, we reach the most acidic solution on our list. Ammonium chlorite takes the crown for being the most acidic of the bunch.
So, from least acidic to most acidic, we have NaOH, NaHCO3, NaCl, NH4Cl, and NH4ClO2.
To arrange the solutions in order of increasing acidity, we need to compare the acidity of the different substances. The acidity of a compound is determined by the presence of acidic species or the ability to donate protons (H+ ions). Here's how you can determine the acidity of each compound:
1. Let's start by looking at NaCl (sodium chloride). NaCl is a salt that is formed by the neutralization of a strong acid (HCl) and a strong base (NaOH). Since NaCl is a result of the reaction between a strong acid and a strong base, it does not possess any acidic properties. Therefore, it is not an acid.
2. Moving on to NH4Cl (ammonium chloride). NH4Cl is formed by the reaction of a weak acid (NH4OH) and a strong acid (HCl). Since NH4Cl is derived from a weak acid, it will have acidic properties. The ammonium ion (NH4+) can donate protons and act as a weak acid, making NH4Cl slightly acidic.
3. Next is NaHCO3 (sodium bicarbonate), commonly known as baking soda. NaHCO3 is a weak base and can act as a weak acid in certain circumstances. When dissolved in water, NaHCO3 can produce H+ ions due to its weak acidic properties. Therefore, NaHCO3 is weakly acidic.
4. Now, let's consider NH4ClO2 (ammonium chlorite). NH4ClO2 is formed from the weak acid HClO2. The chlorine atom in this compound has a +3 oxidation state, which makes it a weak acid. Therefore, NH4ClO2 is acidic.
5. Finally, we have NaOH (sodium hydroxide), which is a strong base. NaOH is formed by the reaction of a strong base (Na) and water (H2O). Since NaOH is a strong base, it does not have any acidic properties and is typically used as a base to neutralize acids.
Now, let's arrange these compounds in order of increasing acidity:
NaCl < NaOH < NaHCO3 < NH4Cl < NH4ClO2
Note that NaOH is not acidic but is included in the order for reference purposes.
How did you figure out the order of increasing acidity.

I don't know if you are to calculate these or not.
Approx pH values are NaOH is about 12, NaHCO3 is about 8, NaCl is about 7, NH4Cl is about 5. You will need to calculate the pH of NH4ClO2. I don't remember those Ka or Kb values. (H^+) = sqrt(Kw/KaKb) and fit that into the scheme above. I think pH of NH4ClO2 will fall as the lowest pH (strongest acidity).
