I want to change font size of text to 14pt, but it's important to me that math font size must be 12pt.
Is there any way to change font size of text without changing font size of math text?
I would grateful for any help.

The Problem lies within the definition of \textsuperscript that uses math mode.
\DeclareRobustCommand*\textsuperscript[1]{%
\@textsuperscript{\selectfont#1}}
\def\@textsuperscript#1{%
{\m@th\ensuremath{^{\mbox{\fontsize\sf@size\z@#1}}}}}
A possible workaround is redefining the actual command so that it will not get in the way with your equations, this needs graphicx:
\renewcommand{\textsuperscript}[1]{\raisebox{0.8ex}{\scalebox{0.66}{#1}}}
Or this needs relsize
\renewcommand{\textsuperscript}[1]{\raisebox{0.8ex}{\smaller{#1}}}
I admit that this is just an easy workaround emulating the typrsetting of superscripts. It might be possible, that modern typography defines super/subscript in a certain way.
This also works with various enlargements of text sizes. This MWE also emulates a textsubscript:
\documentclass[12pt,oneside,letterpaper,titlepage]{article}
\DeclareMathSizes{12}{20}{14}{10}
%% Solution 1
\usepackage{relsize} %smaller
\renewcommand{\textsuperscript}[1]{\raisebox{0.8ex}{\smaller{#1}}}
\newcommand{\textsubscript}[1]{\raisebox{-0.4ex}{\smaller{#1}}}
%% Solution 2
%%\usepackage{graphicx} %scalebox
%%\renewcommand{\textsuperscript}[1]{\raisebox{0.8ex}{\scalebox{0.66}{#1}}}
%%\newcommand{\textsubscript}[1]{\raisebox{-0.4ex}{\scalebox{0.66}{#1}}}

For chemistry typesetting (I guessed that on the calcium bit) there are some packages available, like bpchem or mhchem, that handle formulas quite well.
\documentclass{article}
\usepackage[utf8]{inputenc}
\DeclareMathSizes{24.88pt}{12pt}{12pt}{12pt}
\begin{document}
\Huge Testing the math font size: $99.9\%$
\end{document}
You had specified the math font sizes to use if the text font size was 14pt but your example text was Huge, and size10.clo specifies
\newcommand\Huge{\@setfontsize\Huge\@xxvpt{30}}
so \Huge is \@xxvpt so more or less 25pt, but \DeclareMathSizes needs the exact size so you could use \@xxvpt or 24.88pt as I use above, the latex format defines these shortcuts for font sizes:
\def\@vpt{5}
\def\@vipt{6}
\def\@viipt{7}
\def\@viiipt{8}
\def\@ixpt{9}
\def\@xpt{10}
\def\@xipt{10.95}
\def\@xiipt{12}
\def\@xivpt{14.4}
\def\@xviipt{17.28}
\def\@xxpt{20.74}
\def\@xxvpt{24.88}

You can change the surrounding text font size to
14ptby normal means. And to maintain the math font size to12ptyou could use the\DeclareMathSizesin your preamble. The syntax is:So, for instance, you could set:
Or make all math sizes equal:
It really depends on your requirements! But adding either code to your document's preamble should achieve what you needed to do.
