Why 4 hydroxy benzoic acid is less acidic than 2 hydroxy benzoic acid?
as because in 2-hydroxy benzoic acid, there is a possibility of H-bonding which makes the dissociated ion stable and will not combine with H+ ion leaving it free, while it is not so in case of 4-hydroxy benzoic acid.
How do you remove dried mice urine form kitchen dishes?
Wash them with hot water and soap. Soak for a while if necessary. Rinse in a bleach water solution.
How can separate water and salt without lossing of water?
Get a filter funnel and filter paper and pour in solution . water will run through and salt left behind
When you filter something what is the stuff inside the filter called?
Filtrate goes through the filter while the material trapped by the filter forms a cake...hence the name: Filter Cake.
Why are standard solutions used?
A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
Why is it necessary to filter the benzoic acid while hot?
because it will form solid when cool
Why is benzoic acid is in molecular form at pH of 2?
Benzoic acid is a weak acid, which means that its dissociation is reversible. C6H5COOH -----> C6H5COO- + H+ At pH 2, there are a lot of H+ ions in the solution. According to Le Chatelier's Principle, the equilibrium will shift to the left to favor the opposite reaction where Benzoic acid is produced, to reduce the amount of H+ in the solution. Therefore, an insignificant amount of benzoic acid will dissociate, while most of it remains in the molecular form.
Why is the sodium benzoate easily extracted into H20 while the original benzoic acid is not easily extracted into H20?
Because sodium benzoate is a salt and is soluble in water while benzoic acid is insoluble.

Does benzoic acid have an odor?
Acetic acid is an aliphatic (fatty) acid and a liquid while benzoic acid is an aromatic acid which exists in solid state.
Is benzoic acid or sucrose more soluble in water?

Why must you keep the filter assembly hot while you remove the charcoal?
The filter assembly must remain hot when you remove the assembly or the solution contained within the assembly will crystallize to early.
What is the separation method of sodium chloride and cupric oxide?
Mix with water and filter, Cupric oxide will be filtered away while sodium chloride remains in the solution
Why cant a solute be separated by a solution by filtering?
Dissolve some sugar in water. Try and filter it out. Now, stir some bits of wood into water. Try and filter it out. You've just discovered the difference between a solution and a mixture.
