Generally, the lower the pH, the higher the acidity in the wine. However, there is no direct connection between total acidity and pH (it is possible to find wines with a high pH for wine and high acidity).
What's more, because of its alcoholic content, wine freezes at a substantially lower temperature than water, and even at temperatures as cold as the lower 20s F (minus-6 C), it thickens into a slush long before it hardens into a giant ice cube.
