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.

Answer,
For example, silver ion can be precipitated with hydrochloric acid to yield solid silver chloride. Because many cations will not react with hydrochloric acid in this way, this simple reaction can be used to separate ions that form insoluble chlorides from those that do not.
Answer:
- Nucleus Function - Controls and regulates the activity of the cell.
- Ribosome builds proteins.
- A vesicle structure is kinda like a sac filled with a fluid of sorts.
- Rough ER has ribosomes attached to the cytoplasmic side of the membrane.
- Golgi apparatus kinda looks like a "stack of peta bread"
- Golgi apparatus functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.
- The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
- The mitochondria produced energy/ATP
- Mitochondria have a double membrane arrangement that separates the organelle into four distinct compartments
- The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton
The answer is c because thats the number when combined with a metal. +1 is when its combined with a nonmetal.
