i have the script and i want to add three condition, not sure how to do it.
Kw = 1e-14;
Ka = 1.755388e-5;
pKa = 4.756;
%
Ca = 0.5;
Cb = 0.1;
Va = 100;
Vb = 0.1:0.1:1500;
%
Ma = (Ca * Va) / 1000;
%
Mb = (Cb .* Vb) ./ 1000;
%
for i = 1:length(Mb)
M_excess = Ma - Mb(i);
this is where im stuck!!!!!!!!!
if M_excess > 0
Ma_final = (M_excess * 1000) ./ (Va + Vb(i));
Mb_final = (Mb(i) * 1000) ./ (Va + Vb(i));
Hplus = Ka * (Ma_final ./ Mb_final);
if M_excess < 0
OH = (M_excess * 1000 * (-1)) ./ (Va + Vb(i));
Hplus = Kw ./ OH;
if M_excess = 0
Hplus = Ka * ((Ma_final * 0.999999) ./ Mb_final); ./ (Va + Vb(i));
end
pH(i) = -log10(Hplus);
end

if M_excess > 0
Ma_final = (M_excess * 1000) ./ (Va + Vb(i));
Mb_final = (Mb(i) * 1000) ./ (Va + Vb(i));
Hplus = Ka * (Ma_final ./ Mb_final);
elseif M_excess < 0
OH = (M_excess * 1000 * (-1)) ./ (Va + Vb(i));
Hplus = Kw ./ OH;
else
Hplus = Ka * ((Ma_final * 0.999999) ./ Mb_final);
end
pH(i) = -log10(Hplus);
