Why is it desirable to know the exact concentration of solutions rather than whether the are concentrated or dilute?
Because it's not open to interpretation.
If I ask you for a "long stick" and you come back with something 4' long and I look at you like you're an idiot and say "I said a long stick" because I had something in the 10' range in mind, then that was a waste of your time, right? And you have every right to be miffed at me for not being specific enough the first time.
However, if I ask you for a stick at least 8' long and you come back with that 4' long stick, then I have every right to look at you like you're an idiot and be miffed at you for ignoring very clear instructions.
As it turns out, "concentrated" and "dilute" do have specific implied meanings in chemistry; "concentrated" means "exactly as it came out of the stock bottle" and "dilute" is frequently assumed to be 6 M (which isn't all that dilute; for a lot of common acids, for example, it represents between a 1:1 and 1:2 mixture of the stock solution with water) . However, unless you're a chemist yourself, you may not know this, and assume that you don't need to worry too much about spilling "dilute" sulfuric acid on yourself, when in fact it's a cause for serious concern.
What else can I help you with?
Why wet litmus paper it is used to cheque whether the given solution is acidic or basic?
Because litmus change color depending on the pH: red in acidic solutions and blue in basic solutions.
Is starch more concentration in a tube or in a beaker?
The concentration of starch is the same regardless of whether it is in a tube or a beaker, assuming the same amount of starch is present in both. Concentration is typically expressed as the amount of solute (starch) per unit volume of solvent. It does not depend on the container in which the solute is placed.
How could you determine the solute concentration inside a living cell?
By testing whether it is hyper or hypotonic solution. Also, the water potential!!
What scale is used to indicate whether something is acid or alkaline?
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
What is one word for repeated blows?
One word for repeated blows is "barrage." This term is often used to describe a continuous or concentrated attack, whether in a physical context or metaphorically in discussions about criticism or challenges.
How do you know whether osmosis has taken place?
Osmosis has taken place when there is a net movement of solvent molecules from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. This can be observed by changes in the volume or concentration of the solutions on either side of the membrane.
What do you do if something is 40 percent?
The answer depends on whether the something is desirable or undesirable.
What was your strategy for testing whether a solution of strong acid and solution of weak acid can have the same pH?
I would first prepare solutions of both strong and weak acids at the same concentration. Then, I would measure the pH of each solution using a pH meter. If the pH values of the two solutions are the same, it would indicate that they have the same concentration of H+ ions despite their different strengths.
Why power sharing desirable?
its not desirable coz it reduces peoples powers especially with people who have huge positions whether in church,politics,schools and even in our homes

What do isotonic hypotonic and hypertonic deal with?
A hypertonic solution is one containing more solute, a hypotonic solution contains more water, and an isotonic solution contains equal amounts of solute and water. Whether a solution is hypertonic, hypotonic, or isotonic can determine what happens to the cell. In a hypertonic solution, solute will diffuse into the cell down the concentration gradient. In a hypotonic solution, water will move into the cell by osmosis down a water potential gradient, and in an isotonic solution nothing will happen because the concentration and water potential are the same both inside and outside the cell.
How do you know if a quadratic equation will have whether or not it will have solutions?
Factorise it!
You can determine by the discriminant whether the solutions to the equation are real or numbers?
imaginary
What is the most desirable characteristic for medical product advertising?
The most desirable characteristic would be its effect on sales and brand perception. As far as specifics, it'd be helpful to know whether you are marketing to the medical industry or to consumers.
How much did houses cost in 1994?
As today, it was very varied, depending on how big the houses were, in which country, and whether they were in a desirable district.
