The observation that a solid is dissolving in water is qualitative in nature. If you wanted to make this a quantitative observation you would have to measure the quantities involved. For example, I placed 5 grams of NaCl in a beaker of 100 ml of water at a temperature of 20o Celcius, and did not stir, and it dissolved in 30 seconds. You may or may not need that information. If all you want to know is whether salt is soluble in water, the qualitative observation may suit your purposes. But in general, quantitative observations are more informative and lead to greater scientific insights.

Does amminium hydroxide exists?
Ammonium hydroxide only exists in solution and is formed by dissolving ammonia in water. The solid cannot be isolated
Which of the following does not increase the rate of dissolving a solid in water?
- a decrease in temperature - an increase of the particles dimensions - lack of stirring
Differentiate qualitative observation from quantitative observation?
qualitative observation is the method of identifing a compound such as salt analysis,etc,. and quantitative is the calculation of the amount of a particular compound in a given sample such as asseys..
What would decrease the rate of solution when dissolving a solid in water?
By irritating a solution, increasing the concentration of the solute, by increasing the temperature
When table salt dissolves in water is it a physical or chemical property?
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
Is capacity of water quantitative or qualitative data?
Its the amount of water so it is quantitative
What is different of quantitative observation to qualitative observation?
A qualitative observation merely indicates that the subject possesses a certain quality, for example "this water is salty". A quantitative observation takes a measurement of the quality, for example "this salty water has a concentration of 10% salt".
What is diffirence between quatilative?
I'm going to make a guess you're asking the difference between qualitative and quantitative. Qualitative means what kind of and quantitative means how much of. It's easiest to explain this in chemical terms. Starting with a glass of salty water, you can taste it and say it contains salt -- that's qualitative. If you evaporate the water and measure how much salt remains -- that's quantitative .
What is the quantitative statement?
Quantitative means having numbers and measurements. qualitatitive does not. Qualitative Example: mix hydrogen and oxygen and you get water. Quantitative Example: mix two moles of Hydrogen and one mole of Oxygen to get one mole of water.
What would speed up a dissolving of a solid solute in water?
Break up the solid
What is the different between quantitative and qualitative measures?
If I had a 25% solution of sodium chloride and I did a quantitative measurement, the interest would be in HOW MUCH was present. In this case it would be 25%. If I did a qualitative measurement, all we would be interested in is - WHAT IS PRESENT. In this case sodium chloride and water. In simple terms, qualitative is "What is present" and quantitative is "How much is present"
What is the central difference between qualitative and quantitative?
Qualitative and Quantitative determiners are used before nouns. Qualitative determiner is a describing word or adjective used before noun to show the quality of the noun. Eg.: Beautiful picture Beautiful - qualitative determiner or qualitative adjective Quantitative determiner is used before uncountable nouns to show the quantity of the noun. Eg.: A kilo of rice A glass of water A kilo of, A glass of - quantitative determiners rice, water - non count or uncountable nouns Note: Determiners are also known as Adjectives. Before the countable nouns we use Numerical Determiners. Eg.: Three apples Three - Numerical Determiner apples - Noun Hope I could help you out. All the Best!
Is dissolving Physical change or Chemical change''?
is dissolving a chemical or physical changeWell, it is not. Because you are not changing the chemical identity of the solid. It's still solid chemically and water chemically.
Solid forms into dissolved water is a chemical or physical change?
Dissolving in water is a physical change.
How do you Compare quantitative and qualitative descriptions?
Quantitative is basically the numbers and figures of whatever you have done.Qualitative is the verbal use, so words and descriptions for what you've done.E.g.At school, we did an experiment:Purpose: to see if you put one hand in cold water and one hand in hot water for 30 seconds and then put them both in tap water, would one be hotter than the other?So the quantitative results would be what temperature the water was, how much water there was etc.The qualitative results would be whether you felt the water was hotter or not etc.
Descible what is dissolving?
Dissolving is what happens to sugar when you put it into hot water. It goes from being a solid to being a liquid. Soap, when placed in hot water, will also dissolve.
What is a qualitative question?
A qualitative question is a question that explains what something does without using numbers.For example: "answer what the results of this experiment is in a qualitative question"This experiment went well except some of the water spilled and changed the results.A question that is quantitative is when it actually uses numbers to describe something.
