Kaliumcarbonat (fachsprachlich) oder Kaliumkarbonat (Trivialname: Pottasche), K2CO3, ist ein Alkali und das Kaliumsalz der Kohlensäure. Es bildet ein weißes, hygroskopisches Pulver mit einem Schmelzpunkt von 891 °C und einer Dichte von 2,428 g·cm .

And for acetic acid with K a = 1.8 x 10 -5, pK a is close to 5. A higher K a corresponds to a stronger acid which is more dissociated at equilibrium. For the more convenient logarithmic scale, a lower pK a means a stronger acid.
