Expert Answer:

Milli space equivalents space of space straight H to the power of plus space ions space formed space in space 10 space mL space of space HCl equals 10 cross times 0.01 equals 0.1

Milli space equivalents space of space straight H to the power of plus space ions space formed space in space 40 space mL space of space HCl equals 40 cross times 0.01 equals 0.4


Total space meq space of space straight H to the power of plus space ions space in space solution equals 0.5
left square bracket straight H to the power of plus right square bracket equals fraction numerator 0.5 over denominator 50 end fraction equals 10 to the power of negative 2 end exponent

pH equals negative log left square bracket straight H to the power of plus right square bracket

to space calculate comma
space pH space equals 2
