On the pH scale, numbers greater than 7 indicate which type of solution?

Explanation:
Numbers above 7 on the pH scale designate a basic or alkaline solution. The scale runs from 0 to 14, with 7 being neutral; acids are below 7 and bases (alkaline solutions) are above 7. Alkaline solutions have a higher pH because they contain more hydroxide ions relative to hydrogen ions, which gives them their basic character. This higher pH causes the hair cuticle to swell and lift, facilitating chemical penetration in certain hair treatments. So, the term that matches numbers greater than 7 is alkaline.
