The pH of the finsl solution is equal to <u>2.93</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
C₁ = 0.170 m
V₁ = 17 ml = 0.017 L
C₂ = 0.170 M
V₂ = 22 ml = 0.022 L
C₁V₁ =C₂V₂
0.170× 0.017 L = 2.89 × 10⁻³ ------------- HCl
0.170× 0.022 L = 3.74 × 10⁻³ ------------ NaOH
⇒ 3.74 × 10⁻³ - 2.89 × 10⁻³ = 0.85 × 10⁻³
⇒ 3 + log 0.85
⇒ 3 + -0.07
⇒ pH = <u>2.93</u>
The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

Answer:
The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists, and other scientists. If you get to understand the periodic table and learn to use it, you'll be able to predict how chemicals will behave.
Answer: it’s number 2 add a catalyst
