Go into your glovebox and pull out the cars manual - the big thick book that says "Cadillac Escalade" Go to the table of contents and look under "Fluids and Capacities" (There are different Capacities for different size engines)
Household ammonia has 10 times higher H+ concentration
5.85gms/500cc
Seven items.
The answer is 5 g.
18m is 1800cm
No, they simply form a solution of calcium chloride.
This is correct, but one should add that the solution heats up because of the exothermic process involved when water causes the calcium chloride crystals to dissolve; the calcium chloride is dissociated into calcium and chloride ions.
However, the question is why does the solution test as an acid when phenol red is added? The red solution turns yellow indicating an excess of hydrogen (hydronium) ions. There is no adequate answer that I could find on the Internet.
antacid tablet are chewed because they can act faster whereas swallowed tablet act slowly.
VInegar has the low ph. Ammonia has the high ph.
It is the most effective when it is at pH=pKa of its weak acid component.
Using a pH-meter the measurement is more accurate and sure.
But at home you can use a pH-paper for transparent liquids.
