That is True XD
Hope that helps :D
The answer is PO4^-3 is non-polar.
The answer is the climate of a place. The troposphere is the lowermost level of Earth's air, and is likewise where closely all weather and climate situations happen. It covers about 75% of the air's mass and 99% of the total form of water vapor and aerosols.
The students can determine which of the solutions contains salt through the conductive tester.
<h3 /><h3>What is an ionic solution?</h3>
It is a solution containing ions are atoms that have gained or lost electrons to acquire a positive (lost electron) or negative (gained electron) charge.
An ionic solution would be able to conduct electricity whereas the covalent would not so if you have a conductivity tester which is available in most labs.
The students can distinguish between the 2 solutions through the conductive tester.

Answer:
pH before addition of KOH = 4.03
pH after addition of 25 ml KOH = 7.40
pH after addition of 30 ml KOH = 7.57
pH after addition of 40 ml KOH = 8.00
pH after addition of 50 ml KOH = 10.22
pH after addition 0f 60 ml KOH = 12.3
Explanation:
pH of each case in the titration given below
(6) After addition of 60 ml KOH
Since addition of 10 ml extra KOH is added after netralisation point.
Concentration of solution after addition 60 ml KOH is calculated by
M₁V₁ = M₂V₂
or, 0.23 x 10 = (50 + 60)ml x M₂
or M₂ = 0.03 Molar
so, concentration of KOH = 0.03 molar
[OH⁻] = 0.03 molar
pOH = 0.657
pH = 14 - 0.657 = 13.34
