Why is acid base titration a useful technique in chemistry

1 answer:

Answer: Titration is particularly useful if we want to find out the amount or concentration of a known acid or base in a given sample.

Explanation: Suppose you have just been handed a beaker containing a fixed volume of HCL solution. If you simply just know the volume of the solution, you can titrate it against a reagent (base) to figure out the exact concentration of the solution (also known as molarity)

The solution is placed in a flask for titration and a minute amount of indicator is then added into the flask. The reagent (base) is placed in a burette and slowly added to the solution and indicator mixture. The amount of reagent used is recorded when the indicator causes a change in the color of the solution. Using Stoichiometry, we are then able to calculate the concentration and moles of the HCL solution used up in the reaction.

using the symbol M for the element, write the chemical formula for the compound that forms when element M reacts with iodine.

Anon25 [30]

Answer : The chemical formula for the compound is, $MI$

Explanation :

When the element 'M' react with the $I_2$ to give $MI$ .

The balanced chemical reaction is,

$2M+I_2\rightarrow 2MI$

In this reaction, 'M' is in mono-atomic form and $I_2$ is in diatomic form.

By the stoichiometry,

2 moles 'M' react with the 1 mole of $I_2$ to give 2 moles of $MI$ .

Therefore, the chemical formula of the compound is, $MI$

What is a maximum negative displacement of a wave

AnnZ [28]

The maximum negative displacement of a wave is the same as its amplitude.

As a wave travels through space, its particles are sometimes above the

<em>x</em>-axis (+) and sometimes below it (-).

The maximum displacement from the axis is the <em>amplitude</em> of the wave.

The amplitude of the wave is the <em>same in both the positive and negative directions</em>.

A slice of pizza has 500 kcal. If we could burn the pizza and use all the heat to warm a 50-L container of cold water, what woul

gayaneshka [121]

Answer:

10°C

Explanation:

Heat gain by water = Heat lost by the slice of pizza

Thus,

$m_{water}\times C_{water}\times \Delta T=Q$

<u>For water: </u>

Volume = 50.0 L

Density of water= 1 kg/L

So, mass of the water:

$Mass\ of\ water=Density \times {Volume\ of\ water}$

$Mass\ of\ water=1 kg/L \times {50.0\ L}$

Mass of water = 50 kg

Specific heat of water = 1 kcal/kg°C

ΔT = ?

For slice of pizza:

Q = 500 kcal

So,

$50\times 1\times \Delta T=500$

ΔT = 10°C

Increase in temperature = 10°C
