Answer #1

ANSWER 1
A solution of pH 7 compares to a solution of pH 10 by taking into account the definition of pH.
pH is defined as the negative of the base 10 logarithm of the molar concentration of hydrogen ions.
Hence a lower pH of pH7 will boast of a greater H+ ions concentration than a higher pH of pH10.
In fact being a logarithmic scale, this value increases by a factor of 10 for every 1 point on the pH scale.
pH 7 has more H+ ions

ANSWER 2
When working with acids, the proper way to dilute these chemicals is to remember that adding water and acid releases a large amount of heat. Hence adding water to acid would cause the excessive heat produced to boil over the added water into an explosive rapid gaseous phase expansion. The safer thing to do, is to:
Add the acid to water
