question 1(multiple choice worth 4 points)\n(08.05 lc)\nwhich statement is true for a solution when its concentration of hydroxide ions increases?\nit becomes more acidic.\nit becomes less alkaline.\nits ph value increases.\nits ph value decreases.

Answer

Brief Explanations:

The pH scale ranges from 0 - 14. A higher concentration of hydroxide ions ($OH^-$) means a more basic (alkaline) solution. The formula for pH is $pH = 14+log[OH^-]$. As $[OH^-]$ increases, the pH value increases. An acidic solution has a higher concentration of hydrogen ions ($H^+$). An increase in $OH^-$ makes a solution more alkaline, not less.

Answer:

C. Its pH value increases.
