TABLE 1.

Results of four acid–rock reaction groups.

Groups	Rocks	MB (g)a	MA (g)b	k (%)c	Acids	pH
1	Dolomite	1.9977	0.9268	53.60	Dibasic acid	4.5
2	Dolomite	2.0020	0.8396	58.06	Dibasic acid + 0.3%VES-c	4.5
3	Broken core	2.0031	1.7464	12.73	Dibasic acid	0.5
4	Broken core	2.0015	1.7208	14.02	Dibasic acid + 0.3%VES-c	0.5

^aRock quality before reaction.

^bRock quality after reaction.

^cRock dissolved ratio k = (M_B − M_A)/M_B × 100%; the dibasic acid represents the 3% HCl and 5% CH₃COOH solutions.
