Explain why an indicator is used in titration

Chemistry
1 answer:
stellarik [79]2 years ago
4 0

Answer:

Titrations. Because a noticeable pH change occurs near the equivalence point of acid-base titrations, an indicator can be used to signal the end of a titration. When selecting an indicator for acid-base titrations, choose an indicator whose pH range falls within the pH change of the reaction.

Hope it helped!!

Based on your knowledge of oxygen ion and that Iron can exist as a +2 or a +3 ion. In the formula FeO, what is the charge of the
DerKrebs [107]

Answer:

+2

Explanation:

Oxygen ions always have the charge of -2. Since Fe is in the transition metal stage, it doesn't have a specific set of ions unless specifically shown. In the equation FeO, we would have to have a +2 charge when equalling the two atoms together. So when combines the charges would look like:

Fe_{+2} + O_{-2} = FeO

Aqueous solutions of copper (II) bromide and silver (1) acetate react to form solid
Sladkaya [172]

Answer:

5.63 g

Explanation:

Step 1: Write the balanced equation

CuBr₂(aq) + 2 AgCH₃CO₂(aq)  ⇒  2 AgBr(s) + Cu(CH₃CO₂)₂(aq)

Step 2: Calculate the reacting moles of copper (II) bromide

30.0 mL of 0.499 M CuBr₂ react. The reacting moles of CuBr₂ are:

0.0300L \times \frac{0.499mol}{L} = 0.0150mol

Step 3: Calculate the moles formed of silver (I) bromide

The molar ratio of CuBr₂ to AgBr is 1:2. The moles formed of AgBr are 2/1 × 0.0150 mol = 0.0300 mol.

Step 4: Calculate the mass corresponding to 0.0300 mol of AgBr

The molar mass of AgBr is 187.77 g/mol.

0.0300 mol \times \frac{187.77g}{mol} = 5.63 g

Compare and contrast the terms homologous and analogous.
I am Lyosha [343]

Analogous structures are those structures in different species which perform the same function, have similar appearance and structure but are not evolved together; therefore do not share a common ancestor. Homologous and analogous organs video explains in a simple way.
