Recall how Newton's investigation of light followed one form of scientific method​
d1i1m1o1n [39]

Observation of experiment and intervention in newton's optics. newton followed the principle of light through prisms and the rays transmitted through them as a part of his observation. Various properties of light and its characteristics were exposed.

Explanation:

  • Newton's investigation of light was based on prisms, lenses and optical rays.
  • He stated that lights differing in colour also differed in degrees of re-frangibility.
  • To support his theories newton employed "Proof by experiments" method. Each method was designated in revealing a specific property of light.
  • A phenomenon known as Newton rings were discovered by newton.
  • Newton recognized after pressing together two prisms that there was a transparent spot.

Arrange the following aqueous solutions, all at 25 ∘C, in order of decreasing acidity. 1 = most acidic; 4 = least acidic Rank fr
Akimi4 [234]

Answer:

1. 0.023 M H3O+.

2. pOH = 5.52.

3. pH=9.45

4. 0.0018 M OH-

Explanation:

Hello,

In this case, such order could be computed by means of the pH, the lower the pH the more acid the solution, thus:

1. 0.0018 M OH-:

pOH=-log(0.018)=1.744\\pH=14-pOH=12.2

2. 0.023 M H3O+

pH=-log(0.023)=1.64

3. pH=9.45

4.

pH=14-5.52=8.48

Therefore the order is

1. 0.023 M H3O+.

2. pOH = 5.52.

3. pH=9.45

4. 0.0018 M OH-

Best regards.
