[H+]	[OH-]	pH	pOH	Acida, basica o neutra ?
1,0 x 10-2 M	1,00*10-12	2	12	acida
1,00*10-13	1,00*10-1	13,00	1	basica
0,6*10-12	1,5 x 10-2 M	12	1,8	basica
1,00*10-7	1,00*10-7	7	7,00	neutra

Formule:

pH=-log[H⁺]

pOH=-log[OH^-]

H⁺=Kw/OH^-

OH^-=Kw/H⁺

[H⁺]=[OH^-]=1*10^-7 M sol. NEUTRA

[H⁺]<[OH^-]=[H⁺]>1*10^-7 M sol BASICA

[H⁺]>[OH^-]=[H⁺]<1*10^-7 M sol ACIDA
