Sodium hydroxide added to water?

what happens when sodium hydroxide is added to water? i know that it dissociates into Na+ and OH- but what happens after that which makes the water so basic (alkaline)?

Is this miraculous water or a scam?

Ok, the promoters showed me this water they called cal water.

First they poured some cal water and normal tap water into two different glasses.

Then they add some tea leaves in both water. the tea in the normal tap water doesnt dissolve that well. But the tea in the cal water dissolved nicely.

Also, they added some drops of a yellow impurity substance and stirred both cups. The cal water turned back to normal after stirred, the tap water remained yellow. They said the water is able to detoxify.

also using a litmus test, the normal water was acidic but the cal water was slightly alkaline.

what do you think about this.

a. temperature
b. latitude of the ocean
c. amount of dissolved carbon dioxide in the water
d. surface blooms of phytoplankton
e. salinity
