Explanation:
If 0.0015 moles of NaOH is dissolved in 11 L of water, what is the pH of the
solution?
Answers
Answer:
pH = 10.15
Explanation:
NaOH is a strong base so it dissolves completely.
Calculate your [OH-] first by dividing the moles of OH- by the volume.
0.0015 mol OH- / 11 L = 0.00014
Then, calculate the pOH:
pOH = -log[OH-] = -log(0.00014) = 3.85
pOH + pH = 14, so pH = 14 - pOH = 14 - 3.85 = 10.15
True or false: The phenolphthalein indicator changes colour close to the point of neutralization which shows the end-point of the titration.
Answers
Answer:
True
Explanation:
A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.
Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.
In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.
Hence, the given statement is correct, the indicator changes its color close to the end point of titration.

Which of the following chemical equations follows the law of conservation of mass?
Answers
Answer:
The third choice
Explanation:
The law of conservation of mass tells us that the mass of the reactants and products in a chemical reaction will be equal to one another. Equations follow the law of conservation of mass when they are balanced, which means that they have the same number and type of atoms on each side.
When individual atoms are counted, the third choice has the same number and type of atoms on each side: 1 gallium, three cesium and three fluorine.
