The ph after 17.0 ml of 0.15 m Koh has been added to 15 ml of 0.20 m hclo4 is <u>3.347</u>.
Titration is a commonplace laboratory technique of quantitative chemical analysis to determine the attention of an identified analyte. A reagent, termed the titrant or titrator, is ready as a trendy answer of recognized awareness and extent.
<u>Calculation:-</u>
Normality of acid Normality of base
= nMV nMV
= 1 × 0. 15 × 0.017 1 × 0. 20 ×0.015 L
= 2.55 × 10⁻³ = 3 × 10⁻³
The overall base will be high
net concentration = 3× 10⁻³ - 2.55 × 10⁻³
= 0.45 × 10⁻³
= 4.5× 10⁻⁴
pH = -log[4.5 × 10⁻⁴]
= 4 - log4.4
= <u>3.347</u>
A titration is defined as 'the manner of determining the amount of a substance A by using adding measured increments of substance B, the titrant, with which it reacts till precise chemical equivalence is completed the equivalence factor.

It is a bit like a video game because when you dumb it down, it's basically a small robotic thing that is controlled by a controller. In video games, you have an avatar being controlled inside a game using a gamepad, in surgery you have a little machine inside of a person's body being controlled using a computer.
Answer:
a. P
b. Br
c. Ag
d. Na
Explanation:
The Periodic Table says so
Reactants are the substances that undergo changes and the new substance created from it is called products.
A. Real gases may be expected to deviate from Charles's law at high pressures.
C. Real gases may be expected to deviate from Charles's law near the liquefaction temperature.
