Quantitative measurements are numerical values, they involve amounts and units like measuring things. Qualitative observations appeal to the five senses, like what does the interaction look and sound like
Answer:
Saturated solution
Explanation:
Saturated solution is the solution in which no more solute can be dissolved at a particular temperature.
A amount of the solute, potassium nitrate is dissolved at elevated temperature and on cooling, it precipitates. It means that the solution is saturated at that temperature. <u>Precipitation of the solute at lower temperature indicates that the solution is saturated solution.</u>
A. Acids increase the number of OH- ions in a solution. FALSE
B. Bases increase the number of OH- ions in a solution. TRUE
C. Acids increase the number of H+ ions in a solution. TRUE
D. Bases increase the number of H+ ions in a solution. FALSE
Solution :
Molecular mass of NaOH is 23 g/mol .
So, number of moles of NaOH is given by :
Now, we know molarity is given by :
Hence, this is the required solution.
