What is the saturation point for citric acid and water?
The saturation point for citric acid in water is around 59.2% at room temperature. This means that water can dissolve up to 59.2% of citric acid by weight at this temperature before reaching a point where no more citric acid can dissolve and the solution becomes saturated.
What is the pka of cyclohexane?
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
What is the number of protons neutrons and electrons in the neutral atom bromine-80?
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
What is the percent by volume of a solution formed by mixing 25mL of isopropanol with 45 mL of water?
% V / V (percentage of volume per volume) =? V1 (solute volume) = 25 mL V (volume of the solution) = solute + solvent = 25 mL + 45 mL = 70 mL We apply the data to the formula of volume percentage of the solute per volume of solution, we will have:
What is the concentration of 5 Baume HCl?
The Baumé scale does not directly measure the concentration of a solution. For example, to determine the concentration of nitric acid from a hydrometer reading, you would need to determine the specific gravity and then utilize a table of known specific gravity values for nitric acid at known concentrations. Using the formula to convert ºBaumé to specific gravity: specific gravity = 145/(145-ºBaumé) you get a specific gravity of 1.0357 for a 5ºBaumé reading on your hydrometer. Then you can go to a table of values, such as the one in the CRC Handbook of Chemistry & Physics (mine is 60th Ed., page D-240) for a table that has various concentration values for specific gravity values. In this case, the closest value of specific gravity to 1.0357 is 1.0352, which corresponds to a 7.50 wt% or a 2.129M HCl solution. Hope this helps!
How much pure acid should be added to 50 ml of a 10 percent acid solution to give a 50 percent acid solution?
A 50 ml solution that is 10% acid will consist of 5 ml of acid (10% of the volume) and 45 ml of water (90% of the volume). You're not adding any water, but you want to add enough acid to make a solution that is 50% acid and 50% water. You will need to have a total of 45 ml of acid in the mixture to make it a 50/50 solution, since the amount of water is also 45 ml. You have 5 ml in there already, so you would need to add 40 ml of acid. That would make a total 90 ml solution that is 50% water (45 ml) and 50% acid (45 ml).
How much pure acid should be mixed with 5 gallons of 70 percent acid solution in order to get a 90 percent acid solution?
x=45
What quantity x of a 65 percent acid solution must be mixed with a 20 percent solution to produce 300 mL of a 45 percent solution?
133.33
The amount of water added to the HCl to aid titration could have been 35 mL or 45 mL and would have given the same results as with the approximately 10 mL you used Ex?
during acid base titration a base reacts with acid molecules not with water so when 35 ml solution is diluted with water the no of molecules of acid remains the same.... so reading does not changed...
How many molecules of lactic acid C3H6O3 are in 1 L of a 0.5 M solution?
There is half a mole of lactic acid, 45 grams, which is half of the molecular weight. If you actually want to know the number of molecules; it is half of Avogradro's number which is 6.02 X (multiplied by) one followed by 23 zeros.
What is the solution to level 45 on clusterz?

What is 20 plus 25?
The answer is 20+25=45
What is the saturation point for citric acid and water?
The saturation point for citric acid in water is around 59.2% at room temperature. This means that water can dissolve up to 59.2% of citric acid by weight at this temperature before reaching a point where no more citric acid can dissolve and the solution becomes saturated.
Is ascorbic acid soluble?
Soluble in hot water. Partially soluble in cold water. Solubility in Water: 1g/3ml water. Solubility in water: 80% @ 100 deg. C and 45% @ 45 deg. C.
What is the LCM of 12 and 45-solution?
